Hi Icebox,
Its a shame you feel that way and I do hope you change your mind.
I would say the first thing to do would be to :-
1. Contact “Support” above to ask Achat to cancel and delete your account and cancel any membership you have.
2. Contact your bank / credit card company and cancel any further payments
3. Close down your account yourself by gifting any unused A$ to close Spouses / Lovers / Friends or even Forum if you wish, to be used for community games / contests / events.
4. Leave and do not log in. After a specified period of unuse, your account will go dormant anyway and disappear from the game. It will only appear again if you log in.
I hope you change your mind.
Good Luck in all you do and I hope you find everything you wish for.
