Poor customer service

I took a K Way jacket back to the store that it was bought from due to colour fading and emblem curling up. The item was 6 months old. The store clerk advised me that it would be sent in for repairs and would take 4 - 6 weeks. At the end of week 4 i went to shop to enquire when i will get it back. Shop assistant advised she will phone me back as the call centre was not available. Week 6 still no feedback. Went to shop again and complained about poor customer service. Call center again not availble. Store manager very arrogant when i asked him to interviene. According to him due to the fact that i do not have the proof of purchase i must just wait. He imp**** that i could have bought the item several years ago! Totally wrong way to treat regular customers Mr Manager!
