Bad Service

I upgraded my cellphone contract in January but because it was an early upgrade my package did not take effect and was only supposed to take effect on the 15th April. I called the Cell C call centre and the lady by the name of Pearl couldn't help as she couldn't see any chances that needed to be done and said she'll transfer me to a department called upgrades. The call was taken by a lady called Priscilla who was very rude and was no help at all. Now the new package has done through but Cell C failed to inform me that I'd loose my old minutes and Data bundles that I had from the old packages. THIS IS VERY POOR SERVICE CELL C AND I DON'T THINK THAT YOU DESERVE MY HARD EARNED MONEY IF THIS IS HOW YOU GOING TO BE TREATING YOUR CUSTOMERS.
