Poor service from Cell C

I have for the last 6 weeks been trying to upgrade my contract. I have visited the Cell C shop at Canal Walk four times already where the first two times they didn't have the phone in stock and were awaiting arrival. On third time time which was about three weeks later, there was some admin issue from their side which they promised they will resolve and get back to me the next day which they never did. After another day I went there again to which they rep**** that they are still busy resolving the issue and will revert to me the next day. That was over two weeks ago and they still haven't reverted back to me. After a few days I phone customer care to which they apologised to for the poor service and they said they would process my upgrade telephonically and courier the phone to me. An agent was due to phone me the next day to commence the process which never did. I phone again after two days and again they apologised and assured me that an agent will phone shortly. This was last week Wednesday and I am still waiting for them to call me. I'm really disappointed at the lack of service I've experienced am really considering moving over to another service provider.<br> L.C.
