Extremely bad customer service

Just to make a long story short. My husband bought a pair of glasses R3k at Tygevalley branch. The 8th of May he took a pair of faulty glasses back to the shop. He was assisted by Nina who told him the system was offline and she could not load any info of thr glasses. The glasses are fairly new , as she wanted to send it away for repairs. To be exact it's not even a month old. And I requested a new pair. Thr email of receipt of hr glasses was suppose to been have send ro my email , but still waiting for it. Nina informed him that she will do a handover for thr glasses to be loaded for a new pair. Today NY husband phoned the shop after numerous tries. Eventually Joshua answered. This is not thr first encounter my husband has wirh hi. My husband spoke in English to him and he asked if my husband can't speak Afrikaans. While my husband was trying to explain to him the situation he told my husband not to speak over him. Joshua is unprofessional, unapproachable and not customer centric. He is absolutely rude and gives an extremely bad image to your brand. Thr first altercation with him was in person and he showed no respect for customers. We are still waiting for an email which confirmed receipt of thr faulty glasses. We will rather take our business somewhere else than buying at your stores again.
