I did (used a male name but Im female). They blocked my account, accusing me of being in debt with them (false) and calling to identify myself to get my money back or what I bought changed nothing. Now I have 90 Euros blocked in an amazon account and a hotline staffed with people with heavy east Asian accents and poor language skills that won't help and Im unsure about how to proceed. ETA: I like using amazon for the prices but I don't want them to know my bank account number of too much information about me and each time I need something from them I create a new account with a false name, buy, pay and ignore the account. I wonder if this triggered some automated alarm. BTW: is this illegal? to buy using a false name (an alias). Im in Germany if that helps.
