I've an outstanding balance with a clinic of USD $522.00 (210 312). And I also got a Debt collector mail notice today that says that I owe $368 to the same Clinic. I paid the total amount of USD 522 today (just now) to the clinic through the mychart app and also got the receipt and confirmation of the payment through email. And also have the sample letter to debt collector for dispute also printed (will be mailing it tomorrow).

My question is will I still owe the amount to debt collector even though I've paid to the clinic directly? with a reciept confirmation that I got. And how can I stop the debt collector from reporting it to any credit bureau given that I have the receipt of the payment that I made to the clinic I owed?
