I am not sure how this works or if checked correctly, I am a XXXX XXXX who had XXXX, got bill sent in payment XXXX time they sent refund girl at office said they mistaken it missed my account so next month did sent in again they took payment not working, so figured send what I can medical was over XXXX until insurance XXXX, my XXXX not recognized so only have XXXX. I thought ifhey accepted payment there were no issues last bill got said only {$8.00} paid it full, few weeks later get a letter from their law offices sent in XXXX payments same account number XXXX they had received and processed them, not sure if not working and sending them money each month why they threaten XXXX XXXX, limit info protected by HIPPA as told them, hassle me under doctor 's care and told to avoid stress to much become a risk to my life XXXX if not XXXX. I thought once they accept payment under my account number I would not worry about being turned into collections let alone a law firm and law firm threatening letter, as tried to tell them once I get some of the bills corrected I can work on theirs more but have XXXX who apparently put in wrong billing address for a lady XXXX and bills hers were also sent to me confusing me getting over XXXX bills but never that I know of missed a month of sending them money accept when they called said they girl XXXX and refund payment because they looked up my account wrong which is not my fault all bills have same account number on them so assume same issue but no thinking their sort of messed up on billing if {$8.00} full bill was paid then get collection letter from their attorney which made me not able to sleep all night worried XXXX my credit after ID theft when in hospital and care facility for XXXX years, so please I just mailed another {$30.00} even though the last bill I got said {$8.00} paid in full, no 30 day notice no total of bill on account apparently so no idea how they do their billing before ill have degree in XXXX and do not understand their policies or procedures why they call when they screwed up on check but sent no prior notice before sending me to their attorneys. Or XXXX up my credit its taken years to fix since ID theft also told them not working so surprised they took this procedure and action against me is this they correct way to do this or did I XXXX up help please very upset and confused, XXXX over this issue I thought i was doing it correctly per law and their acceptance of my payments. Never said I would not pay but if turned into collection sort of counter productive in wanting to do right
