I bought something from Google play when I was living in country x and now that I live in country y I cannot install anything that is limited to country y. In order to get Google to "forget" that I lived in country x I would have to give Google my credit card number that is located in country y. I don't want to change my address, all I want to do is make Google "forget" my old address.

Because of that I refuse to buy anything with my Google account
