Pathetic service - Waiting for iPod repair/replace

I bought an iPod in 2014 from IC Eastgate, it gave me problems and I took it back to IC Sandton to send it in for repairs as the unit discharged in a day's time without even using it and the headphone jack was malfunctioning. The unit came back a month later from core group that IC send their repairs to, but in the same condition. They sent it back again and it got replaced after 2 months of hassle. The new iPod started giving me EXACTLY the same problems as in 2014 and as the new unit was still under guarantee, I booked it in on the 24th of April 2015 with IC Vaal Mall. On the 22nd of May my iPod was back in their shop, without them letting me know it was there, I had to follow up the every time. But I went to go fetch it. I took my earphones with to test it, but the iPod was in exactly the same condition as it was when I booked it in on 24/04/2015. It is now almost two months and I am really furious and frustrated with the pathetic service that I'm getting from IC. I phoned them today (9th of June), but they don't know the status of the repair stating that they're having \problems with their service centre". I have all the proof on paper. This is pathetic! I still have no iPod."""
