I've been very happy with ING Direct's Customer Service so far. Never on hold for more than a minute, and it's available 24/7! They seem to be Canada/US-based as well, which is always nice.

The only thing is that once I tried to transfer money between accounts and it was failing. They said that they were doing an update on their systems and I should try again the next day. Jeez, why not just mention that on the website???

ING Direct 24/7 Customer Support Telephone Numbers

Anyways, here is ING Direct's 24/7 customer service help telephone number: 1-888-464-3232

Even though this is the "English" customer service phone number, they still ask you if you want English or French, defies the point, doesn't it?

The number to call from overseas or while travelling is 416-758-3139, but from my experience, I've been able to call toll-free numbers from Europe as a regular international phone call (though it's certainly not toll-free anymore!)

If you have one of their mortgages, call ING's Mortgage Customer Service Department at: 1-877-464-5565 or 416-497-6829

If you're just enquiring about their "Unmortgage" ING Mortgage, call them at 1-800-568-2190 or 416-758-5600

Finally, if you need help with ING's Mutual Funds (which are pretty garbage in terms of MERs, TD's E-Funds are better for most people), call them at 1-877-464-5678 (8:00am to 8:00pm EST)

ING Canada's Institution Number is 614, and their Branch Transit Number is 00152
