Like a gift from above, I received the statements today that  XXXX   XXXX  claimed to have personally mailed on  XXXX / XXXX /  XXXX  . The envelope with postmark shows a very clear postmark of  XXXX / XXXX /  XXXX   from zip code  XXXX  with the following number  XXXX  on the  USPS labe l. I have attached it below and have reviewed the statements that  XXXX   XXXX  mailed and will be disputing the unallowable double charges for which your company is attempting to collect. They are not valid, not legal, to duplicate a co-pay charge that has been paid on the day of an office visit and then charged a second time at the time the billing agent was resubmitting a previously incorrect submission. The individual in the medical billing department made notations that the billing was done incorrectly. The statements show my co-pay amount was paid each time on the date of my office visit. They are attempting to collect a second, unallowable {$20.00} copay for each of the claims they were required to re-bill to my insurance company. I am only required to pay  XXXX  {$20.00} copay at the time of my office visit. I submitted my current insurance cards at each visit and always paid my {$20.00} copay. They are attempting to collect an additional {$20.00} copay on dates I was not seen but days they were resubmitting billing to my health insurance provider because they had billed them incorrectly initially. I am not responsible for fraudulent co-pay charges added to my account for dates I was not seen due to their billing errors. I have proof of all insurance coverage, doctor visits, co-pays made, and know that none of the billing statements presented to me, show a valid debt for which I am responsible. This debt should be removed as invalid and all debt collection activity should be immediately ceased by  Consumer Collection Management , Inc. A ny information shared with any of the  XXXX  credit reporting agencies should be immediately deleted for this debt is invalid. I have proof I will gladly provide that this debt is invalid and not mine and any and all collection activities b y Consumer Collection Management or any  other debt collector, related to these fraudulent charges should be immediately removed from any/all accounts bearing my name.
