Poor Customer Service from FNB

I am extremely annoyed by the service l'm receiving from FNB. March this year l requested to close an estate account, l was advised to pay the amount of R795 which l did and send email to *** with the required documents, also went to Moruleng Mall branch to have the account closed. I went to Northam Plaza on the 05/11/2022 to open a savings account, to surprise l was told the estate account is still active with a balance and disputed the amount and the manager send an email to the relevant department, however to date l have not received any feedback. I emailed the store for feedback, l have send a complaint to FNB on the FNB website on the 15 November and received sms reference number *** and still no feedback received.
