This is what they said:
For privacy and security reasons, we cannot provide details around your specific account closure, but the most common reasons that require us to close Bing Ads accounts include:
1.The payment method on file was not authorized by the account owner.
2.The account was accessed without authorization.
3.The account is related to an account that was previously closed.
4.The account was determined to be high-risk to other customers or advertisers, as stated in our Editorial Guidelines.
As described in the Bing Ads Terms and Conditions, we do not need to state a specific reason for account closure. Please know that we have taken this matter seriously and thoroughly investigated the issue. This decision is final, and we consider the issue closed.
Sincerely,

Even after i tell them i didn't violate any of those points they keep on sending me the same message back....
I even tried opening another account without any success. Are these people unprofessional, and inept or what?
