Atrocious Customer service by Cell C..

I have a Wi-fi contract with CellC which i obtained sometime last year. I have always been happy with the service until recently <br> I changed my banking details in January and advice the CellC branch in Campus Square. I sent all the relevant information as advised by Douglas Askin. To my surprise in the next month my new account was not debited. I have been calling CellC for the past two months and they still have not resolved the issue. I spoke to a Thulu Tshabalala who promised to phone me back on the 30th to confirm the issue but she never did. I also sent the relevant information to a Siyabonga Makhaye to sort this issue out still nothing was done. I then spoke to a SIyabonga Shongwe who really pulled his weight to help me. He promised me that someone will call me from the finance department on 04th May, but still no one has bothered to rectify this mess.<br> I am highly disappointed by the service rendered by CellC. All of a sudden i am told that I owe R500. Which i do not understand how it came about.<br> People have warned me about the bad service that CellC has. I should have know better than not to listen to them.<br> This has been such an inconvenience to me
