I went to the emergency room ( XXXX Hospital, operated by XXXX XXXX XXXX ) in XXXX 2015. As prompted, I offered my credit card information to the financial team, and they began billing me monthly, in the amount of {$510.00} dollars. 

I have statements from XXXX indicating every XXXX of these automatic billings, on time, and without any issue. 

However, I have recently received collections notices from a collections agency named " AllianceOne '' which claim to be on behalf of " XXXX XXXX XXXX XXXX ''. This is unexpected, as XXXX XXXX XXXX is still billing me, as expected, for {$510.00} per month. 

I have officially disputed the validity of the debt with AllianceOne, but have received no indication from them of the validity or proof of the debt. I have contacted XXXX XXXX XXXX multiple times ( over phone and email ) and have left messages with their human resources and their financial departments, but have received no response, email or otherwise. 

I received XXXX additional letters from AllianceOne this week indicating a different debt amount, and still no indication that they have received my dispute of debt ( sent approximately the first week of XXXX 2015 ). 

I am concerned that this may be a fraudulent collections attempt, as I am still being charged as expected on the XXXX-month billing cycle for treatment through XXXX XXXX XXXX, and have not been delinquent on any payments. 

Thanks,
