Bad service

I had a faulty K-way jacket, I than booked in the jacket for repairs on the 19th of June and was told it'll take up2 4-6 weeks. Was advised to call in on the 19th of July to check the process. I than did so with no luck the phone wasn't picked up, I called several times still no one picked up the phone till the 5th week. Asked a friend of mine that works @ Cavendish to follow up on the jacket because they not picking up their phone. She was told that It takes upto 7-8weeks and they will call me. On the 5th week I thought to myself let me get a new jacket sameone from them but different colour while I wait for the 1 that's on repairs. Last week still no call from Cape Union mart Cavendish Square. I panicked and asked a friend of mine that works for them to contact the store as I couldn't get hold of them still on the phone. She than told me that she was told that they still can't find my jacket and they will follow up with it yesterday which was Monday and get back @me. Today I called them again and I was lucky they picked up and was told the same thing that they can't find my jacket and this is now the 8th week but I was told the process will take up2 4-6 weeks. What do I do now? I want my jacket! Never did I receive any communication from them stating what's going on with my jacket. Instead I received a stinking attitude from Kim and was put on hold for a very long time.
