No feedback, No help on a ***** case, just endless transfers from department to department

There’s a ********** charge that went through on the youth account linked to my cheque account. I reported this on the 30th September 2020, and was advised that investigations will take 7-10 working days which I understood and didn’t have a problem with. It’s been over 10 working days and I’ve not received any feedback. No call, no sms, no email, nothing. I have been calling the ***** department to find out if the case is being resolved but I have not received any help, or even feedback on how the case is going. Everytime I call I’ve been told to call the debit card ***** department because that’s where my case is being handled. They gave me the number to call but every person that I’ve spoken to when I called that number has told me that I called the wrong department, they confirm that the number that I called is the right number but apparently it’s the wrong department. I keep getting transferred to the “right” department but nobody ever picks up that line due to “high call volume”. I am not happy with the service that I am getting from FNB right now, there’s no way that I am going to keep calling and being transferred from department to department as if I’m a guinea *** coz I’m not. I want my money back, all of it. I have been very patient and understanding but this is very unprofessional and unfair, and has left a very bad taste in my mouth. These are the numbers that I was provided with to follow up on the case, but somehow have not been able to be assisted coz it’s the “wrong department” yet THEY confirmed that the numbers are for the ***** department; ***-Debit card ***** department, ***-Fnb ***** department. Feel free to check your call recordings because I am not fabricating anything nor am I even exaggerating. I am very very disappointed right now.
