Hi my mom bought a wodrobe at fairprice in Evaton the promised her that someone will come to build it for her they did but after some few weeks the wodrobe is falling apart she went to the store to let them know they promised to come n fix up until today nothing has been done, the service is very poor or maybe they taking advantage of her because she elderly person imagine buying something because you need it but getting the kind of service I think their service n quality is very bad
