Fraud payment to my account

About a monh ago there was illegitimate payment made against my account.  I made a call to customer service and was then transfered to the security department,  I provided the details and was provided a case number.   I was also instructed to remove my payment method and auto payment.  What was not disclosed to me at this call that this would lock my account from being able to make any type of electronic payment.  I found this out the hard way when i disccovered I had no access from the portal to make a payment and then subsequent calls to the billing department, Since then, I have made many calls both to billing and secutity dept only to be told I have to make a cash payment at an xfinity store or mail in a money order.  The closest store to my service address is over 34 driving miles away.  I did attempt to go to a store and make a cash payment at a kiosk but when looking up my account to make the cash payment was provided an error that a payment could not be made to my acccount.  This is beyond frsutrating to me as well as a major inconvenience.  I travel a lot out of the country for my job which also makes my options very limited.  I basically get the same run around on every call with zero resolution.  No escalation paths are also provided.
