Yeah i did not refund on that account either, maybe because you have used different shipping addys before?
no, it's 100% because I used too many gift cards, this also happened last year, I provided some info they asked and got unlocked.
This time they asked for billing statement of a creditcard X with recent amazon order, but the thing was I didn't order anything using my creditcard X so i couldn't provide any statement with amazon order on it (also I had deactivated this creditcard X a while back so couldn't get old statements anymore). I told them that but they insisted on it so I had no other option than make a fake statement. I made and sent one (just changed the last 4 numbers of the creditcard) using my another creditcard statement then they decided to close it
