No Assistance, Bad service

I attempted to change a debit order date as well as my banking details, which when I took out the account was told by the consultant that I could do this YET now when Im requesting it to be done I am being given excuses instead of the service required. Your team leader Vuyo was also of no help nor assistance as according him he hasnt got access to the system yet his sub-ordinates do, how is it that a 'supervisor' cant help? There once again is a lack of customer service from your customer service department. I requested my complaint to be escalated yet was not given a reference number... pathetic...I asked to speak to a senior person or to get back to me yet not possible, all I was told was ok
