ILLEGAL BILLING TO MY ACCOUNT

I HAVE A AMPATH ACCOUNT THAT HAS BEEN HANDED OVER 2 YEARS AGO AND FOR 2 YEARS THEY HAVE BILLED ME FOR AN EMAIL ADDRESS THAT IS NOT MY OWN AND GIVING MY PERSONAL INFORMATION AND FINANCIAL SITUATION TO THE PUBLIC I SPOKE TO THE MANAGER OLEAN WHO FIRST DID NOT WANT TO ASSIST ME BUT QUICKLY CALMED DOWN AND ONLY SEND ME AN EMAIL THAT I DO NOT NEED.

POINT IS I AM BEING BILLED FOR EMAILS SENT THAT ISNT EVEN MY EMAIL ADDRESS... NOW WHAT DO I DO?
