CellC-Worst service (& bad attitude) ever recieved

I have been a loyal C Cell customer for 10 years & have received unbelievably pathetic service recently. Was due for an upgrade 1st Oct '15 & went to Cell C Cresta. Picked the phone I wanted (Black & silver Huawei Ascend G7) filled in paperwork, even changed my contract from previous BB BIS & paid an upgrade fee. Then the new phone opened by STAFF infront of me IN-STORE was faulty. OBF. It froze, mid boot up. Staff took 20 minutes & \managed to fix it". They tried to persuade us to take it but my husband & I refused to take that specific phone. They did not have stock of the phone & placed an order for more. I received no calls for 4 weeks to update me so we went to the store every weekend on our own to check. Still no help. After 4 weeks one was sent to Cresta & after filling in even more paperwork they open the box at the end & realise it was a white one - which I initially said i did not want. The staff got upset"
