Unprofessionalism,lack of customer respect and doggy business practices

I booked my car for service on the 4th of June 2026, while I was on the phone trying to do the booking the guy told me he has to hang up he will call me back which he never did, I called again later that day and told him I called in the morning and he said he will get back to me, he said he was sorry he forgot, we did the booking I dropped off the the car on Friday afternoon as our agreement and explained to him that besides the service I need them to check the car for me land give me a quote of everything that needs fixing of which they agreed. When I left the car the just told me it's going to cost R3500 for the service because it a major service of which I didn't have a problem with .then they gave me a form I filled it in and that was it no quote no nothing. Saturday morning they called me and told me the car is ready I told them I'm not around but will arrange for someone to pick it up Monday morning. Monday morning the 08/06/2026 i sent someone to go pick up the car when he got there they asked him for the invoice, he called me and I spoke to the lady explained what happened she said ok she will find out what's happening, they eventually gave him the car before he left he called me and I spoke to the lady that was assisting him again and asked her to give him the invoice and the quotation I asked for, she told me she will send me via WhatsApp. They never sent a thing around 15:00pm on the 08/06/2026 I called them again and asked where is the invoice and the quote as they still haven't sent the lady told me she will find out as they are busy but I'll get the whatsApp before the end of the day of which never happened. Today 09/06/2026 at 08/39am I called them again asking them for the quote and the invoice that they said they were gonna send before end of business day the day before and again the guy assisting me said he was going to find out and he will call me back.
