Worst Customer Experience

I have had my contract with Cell Since 2003 and I have not missed a payment not once. I requested the customer service centre on my return from over seas to have my limit increased as I knew I had used the phone quiet a bit while travelling, PS this is a limit I had put on myself not Cell C. It is 6 days and still counting with no one giving me updates on how far they are with this. When I spoke to them, I was promised that this would be resolved in 30 Minutes with a maximum of 2 hours. It is now Thursday and I am almost completing the week without a phone. I now understand why that man went as far as putting a banner exposing the lack of service from CELL C.
