On December 29, 2021, I went to KidMed to have 1 ***** test done. I was told that they did not take my insurance and that I would have to pay $150.00 and that would be the ONLY out of pocket fee that I would have to pay. So I agreed to have the test done and paid the $150.00 fee on that day. I was never told that any additional fees were due and was never handed any other bill or balance due on this date. About 6 months later, I received a bill in the mail indicating that I only paid $150.00 and that the actual bill that I owed them totaled $413.46. There was no exam done, only a swab for the ***** test and I was never told that I would be charged or would possibly owe any other fees. They deducted the $150 paid from the total and indicated that the balance due to them was $263.46. I submitted a claim with my insurance company upon speaking with them I learned that they had sent a check over to Kidmed to cover the balance due. KidMed had now received 2 payments for 1 ***** test. I contacted KidMed to inform them that the insurance company had paid them the balance they said was due. KidMed said they would research and if they found that they did receive the payment, then they would refund me. So I then received a REFUND from KidMed of the $263.46 that I sent them. Now KidMed has turned my account over to the ************************ **** saying that I never paid the account which is not true. I have receipts and proof that I paid them. Why refund me if I still owed? I received a letter from the collection company on November 21, 2022 even though I was never ever notified that a balance was still due on this account. I made another payment to KidMed for $263.46 on December 6, 2022 even though they refunded this same payment to me in September. I would like my account resolved from this matter with the ************************ **** because they are saying I also still need to pay them. I made no errors therefore should not have my credit impacted by this.
