Bad service

I bought a trimmer in January 2025 from Builders Warehouse, Woodlands, Pretoria. In March 2025, it refused to work. There was a smell coming from its small motor engine, hence it did not continue cutting or trimming. I took it for repairs back to the store. I was called after three (03) weeks and told that I need to pay just above R500-00 for them to continue fixing it. First, the machine was less than three (03) months, from the date of purchase. Second, the amount I was told to pay nearly equals a new machine or trimmer. Thirdly, I was being blamed for breaking it. I told them to fix it and sell it for themselves because that's basically what they want. They *****ed me, as I bought the machine, and they still want to continue, if I pay for the repairs.
