Worst service from Stax sounds Great/bad

We bought a LG Microwave in June 2023. In Janaury this year it stopped working. We took back as it was not working. The Manager Thabang refused to exchange but sent it in for repairs. No communication has been coming forth, when we follow up we are told it will be ready in 2 days. I went to the store today and Thabang told me it will be ready by Monday. This is the worst customer service I have experienced. I asked her if she would accept not having a microwave for a month and she couldn't answer. STAX Woodlands store has pathetic customer service
