Group incompetence?

How is it a company can give such (continious) appalling service and still remain in business? The words abysmal, atrocious, uncaring, ***********, illimitable and unfathomable do not even come close to to describing the the level of service or knowledge of their product they have. I had the misfortunate to visit their kiosk at the Blue Route mall on the 10th July and things only detoriated from there. Initially there were 3 staff at this small kiosk, one behind the desk and two sitting on the couch opposite him where clients would normally sit. Instead of getting up, the two just scooted a bit across so I had to "snuggle up" next to them. I enquired about switching the debit order from my fathers to mothers account. I was assured that I need only bring my mother in to provide new banking details. I still asked for re-confirmation that nothing more was required and was assured that was it. I went home and got my 80 year old mother to come with me to resolve same. An hour later we were back (the same staff were still on duty plus another had just arrived) and I was now advised a 3rd party form needs to be completed and this is something they cannot do and we need to go to their N1 city offices to do this. How is it 3 staff who were all privy to this conversation did not correct the incorrect advise I was given!!!!!! The 4th staff member (we now had Elizama, Sibusiso, Alecia and Chelsea there from MultiChoice) advised she could switch us from debit order to cash and this would resolve the unpleasant situation. Again I enquired if they switch is nothing else required and was assured NOTHING! The switch was done and I was shown the screen detailing it was now a cash/manual payment and the next payment was due by the 30th July. In keeping with their dreadful client experience reputation, the debit order which I was assured would not come off again came off yesterday. I approached the staff again this morning (think it was Sibusiso and Chelsea on duty) and they could not understand why the debit order had come off again. Now if they dont know, how are we, the clients, supposed to?
