FNB does not downgrade accounts and keeps charging incorrect fees

I requested an account downgrade in August 2022 but am still on a Premier account AND being charged Premier rates in October 2022. I was told it would take 5-7 business days and previously when I logged into my account, my cards section showed I was on an Aspire account. A banker called me in August to do the downgrade but clearly did not process it. FNB has now magically downgraded me but I want my bank charges reversed from August for the Premier fees. This bank has become a joke over the past few years and increased it's fees, changed eBucks so they aren't worth it anymore and customer service levels have dropped. Do NOT use this bank and I'm already in the process of moving my whole banking portfolio from them.
