Poor customer service

I have 2 contracts with CellC currently, one a samsung S6 and a Huawei Ascend Mate 7. <br> I recently experienced a problem with the Huawei where the microphone does not work and the phone is less than 1 year old. <br> I have taken the phone in to the CellC store in The Atrium, Overport where I took out the contract and the staff at the store were extremely unhelpful and said that they cannot take my phone in for repairs without the original contract. I currently do not have a copy of the contract and have contacted CellC customer care without any success.<br> I am surprised that the store does not have a copy of the contract and therefore cannot help.
