Zero after sales service

I have purchase a brand new Ford from Rola Ford Herm**** with great service with alumium canopy (R 30 000) which was provided by Herm**** Auto Fittment Centre After a month the window started to come loose.I took to the fittment centre for repairs.I was told it will take 18 working days for replacement from the manufacturer.There will be zero extra effort for the replacement but come in 2 days time because I don't have current staff to help you today. I made an appointment for 2 days later at 10h30 Arrive on time but I was told it will take 4 hours (You must leave your bakkie here)irrespective if that will suit me. I was under the impression Please come in and it will be done chop-chop.When I told them that's not going to work for me I was told we will take your canopy off which means I can't transport anything because it's exposed to crimminals The owner Pieter is prepare to take his cut/profit when one purchase the canopy (which he is entitle to)but the after sales service he is not worried about the inconvienance it caused due to poor manufacturing of the canopy
