Oh No Cell C - Not Again!!!!!!!!!!!

After months of endless trying to sort out my 2 problems with Cell C, I finally posted my experience on this site and - would you believe it - I had a call from them the very next day. They were so eager to sort out my problems and I finally felt like a customer who was being heard. Today they sorted out my network problem and I am very grateful. HOWEVER I also had a problem with an amount that was erroneously charged to my account and which they had promised to refund - STILL WAITING FOR THIS TO BE SORTED OUT. IT IS NOW 8 MONTHS SINCE I BEGAN WITH THIS QUERY
