Poor service of cell c

On thursday 30 April 2015 I went into Cell C promenade branch to do a contract simswap as my simcard unfortunately just did not have service. The consultant advised me that doing a simswap via Customer Care is cheaper as they charge R114. And that I had to buy my own simcard and call customer care which I did the same day at 14:30. The consultant told me in 2-4hours somebody will call me to do the simswap. The next day at 14:20 I missed a call from them as I was working. I escalated the call again after I received 2 miscalls. I then called at 18:44 an the consultant who I spoke to last tristan said I would receive a call jn the course of the saterday. Saterday passed, sunday passed and monday. I am not able to use my phone as I do not have another micro sim and feel that the service im getting is just disgusting. as the simcard not having any service was not my fault.
