Builders warehouse Hillcrest

I bought a wolf chainsaw from the builders in Hillcrest that was on promotion for R1000 on the 26/11/24 they had none in stock the sales person didn't even offer to see if any other builders had stock, so they sold me the display unit that didn't even have a box . Eight days later I took it back as I was having problems starting the chainsaw as it was giving me blisters on my fingers just trying to start the chainsaw I spoke to the manager asking for a refund and I was informed that it's there policy to send it away for repairs, the manager was rude just said he must send it for repairs and just walked away the manager then said I mocked him buy doing exactly what he did to me I asked the managers how I mocked him and he couldn't answer me . I was called on Tuesday the 10th December to fetch my chainsaw as it went for repairs on the previous Friday I asked the lady at the customer desk for a work order and I was told Shaun didn't do a work order that my chain was to tight and to much oil and now a week later the rope handle to start the chainsaw has come off. On the 17/12/24 I phoned customer care and spoke to a lady by the name of Robyn I told her what happened with the chainsaw and I was told that she would call me back before end of day as she needs to speak to her supervisor and I'm still waiting for that call not sure what kind of service builder's warehouse gives their customers where a manager argues with a customer and that customer service can't even call back when you get told they'll call you back
