Stay away from Builders Warehouse at Eden Meander in George

I bought a circular saw at Builders Warehouse in George on 17/06/2019. I used it about 4 times to cut planks. In December 2019 it just made sparks and smoke and trip my electricity. I took it in because its under guarantee. They called me back with a quote. Now i must pay for the junk they sold me that cannot even cut a plank. I took the plank with to the branch for them to see what i was busy doing. According to section 56 or the consumer protection act they must replace the item or refund me within the first six months now they want me to pay for the repairs. I will ruin that shop. I refuse to pay. every one in George will know about this. Good Luck Builder George. I want a replace or my money back.
