hi
let me take a stab:
1. you cannot change your username
2. if you want account closed, you must email us from that email and ask us to do just that.
3. clicking yes or no does not do much.
4. credits are based on countries, so in your country there maybe 20 offers today and 0 tomorrow. it's hard to say.
5. unfortunately, disconnects are part of the game. there have been long discussions with pros and cons but fact is, that we cannot predict how disconnect occurred... on purpose or not.
