Non existent service

Needed work done on my volvo xc90 and phoned supa quick. spares need to be ordered, and they said they would inform me when arrived. They did not inform me and when I inquired the spares had in fact arrived. I drove there, was told to drive to the back ramps and would be dealt with there. I am disabled so cant sit around for long periods and informed the counter of this on numerous occasions. I arrived t the back and stafff were busy with 2 cars while some staff lounged on the large tyres doing nothing. I sat in the full sun for 90 minutes. in that time no one approached me or updated me. On inquiring 90 minutes later I was told there were cars ahead of me, which is fine however then tell me upfront. I acted like most South Africans should and drove away to spend my hard earned money somewhere else. I was not even phoned by the franchise to ask what happened. Then we as South Africans have the cheek to say the economy is bad when even the most simple of services cant be carried out
