Makro falling to pieces

On Sunday the 24 of February 2019 my mother and father went in to the pietermaritzberg branch of makro to purchace a new tumble dryer , when they got home and opened the product and started to use it there where a number of faults and problems, now my mother and father have been on the phone with makro pietermariztberg since Monday the 25th and have had no response back even when makro promises to call them back, they have been told that today on Wednesday the 27 of February 2019 that they will come and replace the tumble dryer , only to have Densile phone and tell them in not possible and that they would have to wait another week before they could get a product that actually works , which is absolutely pathetic, he the proceeded to start a shouting match with my father over the phone , now this service is absolutely pathetic, what does it say about makro that you can buy a product brand new in the box and get how and its falling to pieces and then they can't even keep there promises of replacing it , I guess makro pietermaritzberg doesnt care about it's own warranties
