Disgusting service

Disgusting service. I called through on 24th November to change debit order account details. I was told to email letter and Id. Did so but no reply since. Called back today. Told to email docs again. Received and went for assistance but after holding on the line for an hour and had to hang up. Called back on the line with consultant for about 30 minutes to be told cannot debit business account. Very unhappy with getting 2 different stories so I asked to speak to a team leader/ manager. He refused to speak to me. I was told by consultant Thandeka that his name is Mhlengi Khumalo. This kind of service is very unprofessional and disappointing. As a leader he is supposed to be assisting clients and upholding the brand
