Faulty new cellphone received-Still no replacement

I renewed my cell contract on 17/12/2015 and obtained a new cell phone. The unit was used for a few days. Unfortunately it would just switch off randomly. I returned the phone to CellC to be tested and replaced or fixed on 22/12/2015. Called CellC yesterday who informed me that the cell is faulty a new unit will be provided. I still have not received a new cell phone from CellC. Almost a month later and I still have not used the new phone on the renewed contract.<br> OBF - 173979<br> Now I am being told that the Klerksdorp branch will supply me with a replacement, but I need to pay for the courier cost. WHAT? Poor customer service from Cellc. This is unacceptable. When will CellC provide a good service?<br>
