After asking A-1 Collection Service of XXXX, NJ for copies of the original invoices from XXXX XXXX XXXX they sent me XXXX statements then sent me XXXX invoices each for the total amount. They also reported all XXXX invoices to the credit reporting agencies making it appear that a disputed amount of {$1400.00} is {$5700.00}. 
The statements they sent me in proof of debt owed ( after a 3-5 year period ) have handwritten amounts due on otherwise computer generated statements. 
I dispute all XXXX statements as I paid the normal office copay of {$20.00} at each visit. It appears that the hospital owning these practices has reclassified the visits as something else with multiple charges per visit. 
I have contacted the insurance company I was insured with at the time of these charges and I am waiting the receipt of the Explanation of Benefits for each visit. 
I am attempting to determine what amounts I paid each practitioner, but as the services were performed during XX/XX/XXXX, XX/XX/XXXX and XX/XX/XXXX it is difficult to gather that information. Also, I pay bills from invoices and only received statement copies from A-1 Collection.
