Close my account

On 26 October 2022. I settled my account and then asked the lady I spoke to over the phone to have the account closed. She then said it had been closed and this would be updated on the 12th of November 2022 when their books update. I then called again on the 18th of November 2022 and asked for a settlement letter and when received it read that the account was settled and this would be updated on 12 December 2022. However till this day my credit reports how's that my account is up to date and not closed which is not what I asked for. I'm exhausted of calling a company I don't owe a dime to close an account which should have been closed two months ago. I've called one too many times and emails are not rep**** to in a timely manner. Close my account because I have given you guys 2 whole months to do so. Geez!
