Terrible service on ***** cases

I have been banking with FNB for many years now. I have never experienced such bad service. I have opened a ***** case and received an sms on the 29th January 2021 and was advised it will take 21-30 working days to resolve, however it has passed that and I still have not received any feedback. I have emailed the person handling my query with the relevant documents on the 29th January 2021 and didn't get any response from that person. I email that person again on the 6th December 2021 for feedback and still never get any response. I have also tried calling and chatting on secure chat and get the run around. I have emailed care@fnb on the 22 December 2021 and no feedback.

This is extremely frustrating.
