Sunglass Hut won't fix my sunglasses

I bought my sunglasses on 22/11/2015. Since then, a tiny chip has emerged. I took them back to Sunglass Hut thinking their 'ASSURED QUALITY trade in pairs that don't meet the highest standards for up to two years' would apply.<br> <br> I was told I need to call a call centre as the pairs that go in for repairs are ****** from the shop and that the retail attendant 'didn't want to pay if they went missing'. I called the call centre and was kept on hold for 10 minutes.<br> <br> Hardly the excellent service you preted to promise!
