Bad Service

Good day, I'm writing this message regarding to the poor service I continuous get from Cell C. For the last 6 or so weeks. I'm using a Lumia 800 which doesn't allow me to use the *147# ussd. For a year or 2 I been calling the call centre to buy the data bundles but since the last 6 weeks the call centre agents tell me that my account is giving them an error. They can't buy the data for me. They give me a reference number and promise the matter will be resolved but until now the problem still exist. Now I hate even to call your call centre cause I need to explain one and the same thing over and over again. These are some of my reference numbers I got: *** *** SD******001521 *** Your whoever decides to close a case doesn't understand that the case should only be closed once the problem has been resolved!?? I feel the sentiments of this other Sandton customer describing Cell C as the useless service provider. I spoke to Thobane / Thobani Zakwe from the technical dept. who also promised to resolve the issue and call me by 1pm today but never did.
