3 months waiting for a Renault part

The panelbeater responsible for repairing my Renault Modus 1.4, Targus Panelbeaters in Centurion, has been waiting for more than 3 months for 2 window winders. If its not 'stock unavailability' its 'warehouses relocating' or 'the parts are being shipped from Durban'..by bicycle no doubt. Young buyers beware. DO NOT BUY RENAULTS UNLESS YOU CAN BE WITHOUT A CAR FOR MORE THAN 3 MONTHS DUE TO PARTS UNAVAILABILITY!!!!
