Call Centre

I was on the phone for 20 minutes trying to dispute a debit order ( I was assured last month that it would not go through again). I was transfered 6 times... I entred my ID 6 times, approved the authenticaton 6 times and then the call was stopped. The amount is to big to stop via the app. to complain about the call center on the FNB app means nothingnothing!
