Most pathetic customer service ever

After my phone went in for repairs and was deemed irreparable, I decided to upgrade my contract with cell C and get a new phone. This was the worst mistake ever. After being told it would take 72 hours for it to reflect so that the upgrade was possible, it has been 6 days, and has only been escalated today, after over 8 calls to cell C. They have now told me it would take another 5 days before I could get my contract sorted out to start using my phone. The excuse given was that the previous consultant didn't escalate the problem till I called them for the 8th time. Until then, and for the previous days, I was told that the problem was being worked on but it never was. The customer service is pathetic, and I will never use their services again. Each phone call was a struggle being transferred between departments for over 40 Min's, all to tell me that it is being worked on and to wait, until 6 days later to find out no one had done anything about it yet, and to wait another 5 days. This is really shocking.
