CELL C does not deliver

I have tried for a week now to find anyone from Cell C to assist with my wife's phone. <br> <br> Her iPhone 5 Sleep/Wake button has stopped working.<br> No one from CellC seems to know anything about this recall?!<br> My iPhone is confirmed to be part of a batch with the manufacturers fault. And as a result, Apple have issued a global recall of all qualifying devices. We have confirmed this on the Apple website by entering the phone serial number.<br> <br> Apple assures us that our service provider is responsible for processing this repair and it will be a free repair.<br> <br> Cell C help me please! Or should we rather migrate ourselves to another network?
