Bad service

The service I recieved from the Durban branch was reallu bad and unproffesional. I spoke to Nokukhanya who works as a consultant to help me settle my sisters account she did and say my clearance letter would come out before 12pm as we made the payment in the morning. I reapeted several times that she must be honest about when I would recieve the clearance letter and she constantly said before 12pm I payed my sisters account once I had payed I called later on during the day to hear what is happening with the letter and she kept saying later and she would get back to ne which she never. From the 29 of August I had been calling about it. On the 1st of September I tried to call again and spoke to the supervisor Bongi and I told her how many times I had called for the clearance letter,she was very rude to me and said she sees no need for what I am telling her she took my details and said she will go to head office to get it sent. On the same evening I received a call again from Nokukhanya asking for another online payement as she said the bill was incorrectly calculated, I paid again hoping to get my clearance letter. I Then continued to call continuously to find out what's happening as they again said I would recieve it after 12. I Again called and spoke to Amanda who says my clearance letter was sent in which I have not received I have asked them to resend on different email addresses and they have not at all. I am very unhappy with their service their treatment is horrible and the supervisor is too aggressive and rude to be in that position I really wouldn't advice anyone to use their services as it is very unprofessional and frustrating.
