Pathetic service

Customer service at the Liberty Midlands Mall branch of Sunglass Hut is absolutely appalling. My boyfriend purchased a pair of sunglasses on Saturday the 12th of October 2019, on the 16th of October (4 days after purchase) upon taking the glasses out of its case the pin on the side came out and the glasses broke. He went to the branch on Thursday the 17th of October (5 days after purchase) to rectify the situation and to get a refund on the sunglasses. He was then told he would not be able to get a refund as it was a sale item (consumer rights state that anyone is entitled to a refund within 7 days of their purchase) this was ********* on the part of sunglass hut. He was then told they are not able to do anything and he has to contact the manufacturer directly and they will assess the product which could take 3-8 weeks. He contacted the manufacturer and they told him someone would be sent out to collect the sunglasses for an assessment however nothing of that sort was done. He then went back to the store today on the 21st of October 2019 to try and resolve the issue and was told by the workers they would contact the manufacturer and get back to him however nothing was done about it. Sunglass Hut infringes on consumer rights and has absolutely disgusting customer service. The floor workers and even manager have no idea what they are doing.
