Rude consaltant and very bad sevice

I have spend more than R 300 on airtime trying to get hold of an consaltant from debit dispute I have explained from the first consaltant that I spoke to that my network coverage is very bad, I cant verify my account using an App. I asked if I cant use the card number and pin. They consaltant cut off the call while I was still explaining ,I had to call again and waited 1 :30 for my call to be answered, your service is very bad and your consaltant are very rude. This is mynlast month banking with you I am done.
