Unhelpful staff and thrown from pillar to post

i purchased a new cell phone, which meant I needed a sim swop, I went to a vodacom store and was told that my account is registered under a RMCA contract, therefore I will need a written letter from Edgar's before they can do it. I called Edgar's call centre and asked the lady which store should I go to, and I was told that I can go to any store, anytime. I went that afternoon to Eastgate mall, I was told that it needed to be done during office hours. On Monday I went to Edgar's in Newtown junction, I waited in the queue and had a staff member abruptly approach me as to what I wanted, I told him what vodacom required from me and without any help or friendliness, he said they cannot assist, I then told him I was sent there, but another guy from the opposite side of the counter said we cannot help you. I got angry with the way they spoke to me and the approach, and asked to see the manager, she was right there and was more rude and abrupt than the other 2 guys. Her name is intumeleng and she was extremely unhelpful and offered no assistance, she even looked at another customer and laughed at me. <br> <br> Till now I have not got anything done and I still cannot get my sim swop.
