No responce

What a let down. My sister recently took out a contract with Cell C for a Sony Xperia Z5 but was soon disappointed to find out the phone overheats. We took the phone back the next day and it was send through to the service department. It is a week later and still no feedback regarding the phone. It was brand new out of the box, should it not have been replaced as this one was a deflect?!? I surely hope they are not expecting us to pay a cent with regards to this contract as we still have no phone.
