Bad service

I brought a Renault Kwid in for a check up at Renault Tableview, as the car started giving problems after they serviced it,the lady that assisted me was so cold when I brought the car in because I came after 9:00 am and I explained that I stucked 2x won the way to them,she said the diagnostic is about an hour and they will make contact with a quote of what need fixing,it's 10:40 now ,they didn't make any contact,I contacted them,they said their service specialist or someone will contact me but no one made any contact, it seems they just parked the car there and left it, but the car was booked for yesterday.We use the car for business and they waisting time and simply don't care or value clients time,it's really disappointing,unprofessional and unacceptable to get such service.
