Broken PS4 remote returned, 5 months no feedback.

I bought a PS4 Destiny bundle in Dec 2014, with extended warranty, from Ephraim. The remote was faulty. I took it back within 7 days to have it exchanged. Abdul took copies of all my slips and details and said it would be sorted within the first week of January 2015. Since then I have been to Dion Wired several times to follow up on the issue with no luck and too many excuses. It's been 5 months already and still no luck. I went there the last time on the 10th of May to speak to Abdul and he blamed Ephraim. I then spoke to Ephraim and after all the excuses he gave me, I told him the issue must be resolved within a week. He then again asked me for all my slips, because they have lost it. Today I phoned him and he said that they have booked the remote in and I would receive a new one in a month, if i'm lucky. I'm fed up driving out my petrol money and phoning my airtime to try and sort out a problem which wasn't my fault from the start. What use does the extended warranty have if they give such poor service. i'm fed up for the excuses!
