So dissatisfied with the service

I bought a microwave last year at game Kenilworth and it just stopped working and I called and was told bring it back for replacement. I took an ubber which costed me R120 just to be told that it will be sent to the supplier and I would need to wait for 21 days. When it is back I will have to go to the store and fetch it at my cost . The manager Shamiema Radeyemer stated there's nothing she can do.
