Don't get a contract with Cell C, you will end up regretting it

I wrote a review here a few months ago, complaining about the customer experience I have had with Cell C, and sad to say that this still stands. They debited my account when I had cancelled my contract with them. They got in touch to explain that because accounts are charged in arrears, the amount they deducted would be due to me and credited back to me. I understood this explanation. I am now enquiring about my refund and they're giving me the run around to return my money even though I have it in writing that they said this amount is indeed due to me and I have a credit amount on my statement. A consultant yesterday said that this amount would be returned to me and now today are backtracking on this. Come to find out the consultant has the wrong end of the stick and yes, this amount is due to me, even though they were arguing with me over the phone about the legitimacy of my claim. I will be waiting patiently for my refund now but the mere fact that Cell C treats their customers like this is disgusting. I have been loyal to them since 2008 but no more! Please do yourselves a favour and DO NOT get a contract with Cell C. You will end up regretting it. They're quick to deduct money but when it comes to correcting their mistakes and refunding you your money, they will give you the run around and disrespect you on top of it. Please learn from our mistakes.
