im getting this error. I used employee cards and personal with no success. I know they use AVS like google. But i tried every possible combo of ip, business CC and personal CC, and CC info. Any insight is appreciated. I'm sure i can help you guys in other aspects.

By the way this is the message showing.
I can't speak this specific error message, but in the last few months Bing has gotten much more aggressive about banning accounts and/or just blocking questionable accounts.
If this is something you are comfortable calling them about, that is the route I would go.
Alternatively, you can read their help section on billing issues here http://help.bingads.microsoft.com/ap.../3/en-us/52035
Spent over $xxx,xxx over the years with Bing Ads using PayPal as my payment method. When I used credit or debit cards that's where I ran into issues.
