mine worked! i just bought a 200 worth of vanilla prepaid card and just bought a sedu flat iron online. i guess u forgot to register ur card first ;) try doing that before purchasing online.

Do NOT buy this card people...in fact do NOT use Mastecards at all. Its time to put these scam artists out of business. I made the mistake of actually buying a 2nd prepaid card hoping the issues with the first Vanilla card may have been a fluke...no such luck. They charge you for trying to sign onto sites online to use these sites to purchase items such as video gaming online or any site for that matter...and when you are unsuccesful signing in...they charge you for that attempt and steal your money. They will not answer their pathetic help and customert service line either. What a f#$%ing joke that this type of shit is permitted by our government to exist and rip unsuspecting people ooff of their hard earnred money. A$$$$$$$$$$$$$$$$$$$$$$$$$HOLES is what these scaM ARTISTS ARE.

the same thing happened to me ...you have to go online and register the card and then you're set to go

The reason you cannot use automated fuel dispensers with these cards is the problem with the authorisation system. As the fuel dispenser doesn't know how much fuel you are going to take and has to know in advance that you have money to pay for it it has to take a 'pre-auth' due to the lack of knowledge on the amount the fuel pumps have gone down the line of just requesting either 1penny or 1 pound / dollar. This is surely better than assuming you're going to take £100 worth of fuel and taking that as an auth then not returning the difference until the next day?

Therefore because prepaid cards are anonymous and therefore impossible to track down, issuers cannot allow the use of these machines and block them based on their merchant category code (in the case of mastercard) in order to prevent people leaving just enough to cover the auth on the card then anaymously driving away with any amount of fuel they wish.

Maybe you should try reading the terms and conditions before purchasing a financial product then you wouldn't be surprised. The card will only fail if;
A) You are attempting to use it online without registering it,
B) You are attempting to use it in an offline terminal (tricky one this as it's hard for a customer to know, but you should be able to ask the merchant and they will advise),
C) If you are attempting to use an automated fuel pump (shown in T's & C's) or
D) Unfortunately if the merchant will just not accept which is simply their ignorance as there is a big MasterCard logo on the front!?
E) If you are attempting to purchase other financial products as this is against the Money Laundering Regs in most countries - if your from the states it's in the Patriots Act and in the UK the Money Laundering Directive set by the EU.

It sometimes takes the cards an hour to be fully activated after the purchase even though it says it is ready for use. You also will have to register the mastercard online in order for it to properly work at most online stores. I have used them for world of warcrack, steam, and think geek and never had an issue.

All cards must perform something called an AVS check when taking e-commerce payments, this requires the card having an address registered to it - if you've just bought it off the shelf then it will not know your address!

I have never had a problem using the prepaid Vanilla Mastercard. It is accepted everywhere I need to use it and, in fact, acts exactly like a mastercard without the hassle of interest payments...

Your use of the English language and grammar are so bad you do not merit a logical response. Go back to school then maybe you will work out how to use a card.

Nice try..... pressing 0 does nothing loser

"THANK GOD" for your advice......I had waited over 10 days to try to find out how to get my $500 back from this stupid card. For EVERYONE that is reading this message......do take this advice from this customer service .......call that number 1 800 652 9174......then press 0 or # several times back and forth until you clear through that stupid automated lady.....then you will access to the customer service...."thank God"...finally found a customer service...HAPPY!

You were probably declined because whatever you wanted to purchase was over 25.00...If you wanted to purchase something for 50. You would have to buy a 100.00 card. I bought a card for 50.00 and actually got to spend 22.00...they have been holding 28.00 of the money on me for the last week. I had one before and they did not do this . I purchased a second one and it seems that each time I purchase an item they put the exact amount on hold for 7-10 days. So if you want to spend 10. they take 20.00 ...they will give it back someday they said. Customer service reps were extremely rude and actually answered me back in capital letters like I am an idiot for asking for my funds to be released. The place I was trying to use the card for cancelled my membership and now I will have to sign up again and pay a fee to them for joining again. This card is garbage and the people that work there are rude. Good luck getting the money from the card ...or even using the balance of the card.
