Lost UserID/ Need to make a payment

Hi,

I had to suspend my account/ wireless number as I moved out of country.

So I no longer has my wireless number.

I still had 2 - 3 months remaining of my contract so when I suspended my account, I was told to get my final bill around early November.

I tried to log in to my account on Att.com but my user ID (which was my wireless number) isn't working (I guess that's because I no longer has my number.)

I am not in US now, I do not know how to log in to my account and make the payment.

Can someone please help me with this problem?

1. Can't log in to my account (my wireless number is suspended which was my userID.)

2. I need to make the payment of my final bill.

3. So I can unlock my phone to use it in different coutries.

Thanks!
