Business ProfileforAmeris Bank

My home mortgage is through Ameris Bank. On March 29, 2024, I paid my mortgage ahead of time. On April 1, 2024 Ameris Bank charged me twice for my mortgage. My mortgage payment is $1760 monthly and I had that amount allotted in my checking. When they charged me twice, my bank had to pull from my savings account and charged me an eight dollar transfer fee. I immediately sent a message on Ameris Banks online portal. The response to my message was that they did NOT charge me twice and to email a bank statement. I emailed the bank statement that same day, April 1. To this day I have not received a response. I called Ameris Bank yesterday, April 3 and the woman I spoke with, was completely unhelpful. At first, she told me if she needed my bank routing number and account number. When I questioned her, she told me that is how they refund a payment. When I asked her how I would have known that due to no response from the company, she did not have anything to say. She then told me and that they were in the process of refunding it and did not ask for my account or routing number again. She said they had everything they needed. I still have not gotten a refund at this point, I need a refund on the payment and the eight dollar transfer fee. Most people cannot take a hit of a double mortgage payment. I am lucky that I could, but there is no reason why it should take any longer to get me a refund. Additionally, there is no reason to need my bank information to refund this payment.
