Yahoo Voice Locked My Account

[ibanez13]

I tried getting a number from Yahoo Voice, and the order wouldn't go through. I did the live help thing only to find out my account has been locked. A day later, I got an email from someone at Yahoo Voice requesting the last 4 digits of every credit card I ever used with them. It's been 5 months since the last time I got a number from them, and don't remember all the credit cards I used.

I only have 4. Think I should send them all 4 and tell them to take their pick?
