I bought a kitchen scheme at Fair Price Middelburg Branch and they didnt tell me before purchasing it they now tell me after complaining that they dont have guarantee or warranty on the kitchene scheme. The sales lady was Mpho when I call in store the manager says she spoke to the RAM about it abd I wont be helped. How do they sell stuff with no guarantee. This kitchen scheme was chipped same day after assembling it now the drawers are falling off
