PEP mobile phone trouble

Just want to share my unhappiness with the bad service of this company, we bought a Samsung cellphone from PEP Bluewater Bay for our gardener as he was constantly battling with an old phone. Now only 4 months after the phone was bought it stopped charging, the phone was booked in by them and sent to Vodacom Greenacres, about 4 weeks after he received the phone back with the same issue where absolutely nothing was done, i Have just been to PEP Bluewater Bay again and they want to book the phone in again but they require an ID why for heaven's sake? Why do they now inconvenience me and my gardener because they didnt deliver on their customer service? so this means another 4 weeks of wasted time where nothing is being done. I did try to get hold of Vodacom and the PEP area manager but no luck. I hope this message gets seen by someone in charge as we cannot allow companies to get away with such bad service towards the people of South Africa.
