Pathetic Service from Cell C Traderoute Mall

I am experiencing terrible service from Cell C Traderoute Mall in Lenasia, the manager does not show any empathy towards my query to them. I upgraded my phone on the 8th of September at the Cell C store only to find out a day later that this phone is faulty but since I could not get time off to take it back to them I only got time to take it back to them on 12 September only to find out I am going to stay phoneless and unreachable for up to 7 working days. They do not even offer a loan phone in the mean time that to me is pathetic I am even considering canceling the whole deal and go were I will be valued as a customer who has never skipped payment to Cell C in the 14 years I have been with them. Do they consider that some customers might be using their phones to run their businesses? I will never recommend anyone to use/support that particular store.
