3 calls logged but 25 days later non resolved

I Think Iam loosing my mind when it comes to cell c, where do I even begin with cell c, I have logged 3 different Calls with cell c since the 1of August til today non has been resolved. 1 it was for my refund that cell c over debited me for, I have sent the POP and bank statements they required 3times already but still no refund, I've been phoning still NO refund. 2 I have not received by data benefit for August.. I called in and I was told I used it and they'll send me the data validation report...they sent me an incorrect report for a different number.. quoted an incorrect ref and addressed me to someone I don't know. I have called and email to get that rectified till today Nothing has been sent.. 3 I have cancelled a contract that I was due for an upgrade in July because of their poor service, I paid till the 1st if August..I received my benefits in July but I did not used them because the debit order did not go through, my services were cancelled .I was called to make payment which I did, but I could not use my data since the SIM card is deactivated, I have been calling to find out how then can I get my data since I did not use it because the services were cancelled and now the SIM is deactivated... Till today no help from cell c... Iam calling everyday the service is poor, they hang up and rude no one once to assist... My frustration are at peak with cell c and I will never never recommend it to anyone.!!!
