Business ProfileforAiken Regional Hospital Accounting

I was seen at Aiken ER on ****-23 and again on ****/29-23 for *********. I did not receive a billing statement until near the end of April. I started making monthly payments on each account, one was for $476.76 and the other $370.01 in May and was told that as long as I made payments it would not be turned over to collections. After making payments in August of 2023, my account was turned over to collections. I owe $151.76 on one account and $45.01 on the other, totaling $196.77. My intent was to pay them both off in September, but I get a notice in the mail from a collection agency saying I owe $226.76. I am furious that I was turned over to collections. I went to Aiken Regional to discuss this and was told that if I still owed a balance after 6 months the accounts automatically get turned over to collections. I last made payments on ****-23 and the date on the collection letter is ****.23. IT HASN'T BEEN 6 MONTHS YET!!!!!! There is absolutely nowhere on the billing statements that state you will be turned over to collections after 6 months, well 5 months in my case, or I would have paid it by now. This could affect my credit score and report and is very unprofessional of Aiken Regional.
