Let me PROPERLY delete my account
After a truly horrible experience with Bing Ads, from start to finish, it would be good manners to at least let me delete my account. When I say "delete", I use the meaning that everyone else uses, not Microsoft's version, which seems to be "mark the account as deleted but really it's just the exact same".
I don't want any more emails from you trying to improve my non-existent ads, I will never use you again.
I don't want any more obscure emails about billing when my account is at zero (although you owe me money).
I don't want anything to do with you, remove my information.
