Bad service

On the 5th of December 2018 I took my car ford ecosport to human auto motors kimberley for my 80 000km service when I arrive there at 8h20 the consult Juanita said I have to pay cash I said to her they need to work out a quotation before they proceed with the job.Juanita contacted my that after noon at 16h24 she gave my the quote of r950 .00 I said to her they may proceed with the job and how long will it take because I'm leaving my office at 16h30.she said they will contact me so that the driver can pick me up to make payment when they done.At 16h56 she called me to say they are done with my car. At around 17h10 I arrived at their office to collect my car and pay for service that was done .When I ask her (juanita) she said that is r2900.00 that I have to pay. I said to her this wasn't the amount that she quote me.because i don't have that kind of money I would have never agree on that amount .because I don't have that amount of money this time of the month.i asked her what was the amount that they charged for labour she said is was for 1.3 hours.i mean from 16h24 to 16h55 not even 30minutes.They kept my car that day because of the money that I don't have.She and the acting manager (Hein)said o must just know thay all their calls are being recorded will go and listen to their recordings the next day and will get back to me.i was waiting the next day until 15h55 when she called back and said they will only be able to give me r200.00 discount.I said to her I'm unable to pay that amount I request the telephone recordings as they stated the previous day. She said the recordings did not work.they kept my car for another day the Friday 7th i sent my husband went to pay r950.00 they refused to take the money she said I must collect my car they will cancel the service in the service book and will replace all the old parts back .since that day I request them to put everything in writing the reason of cancellation of service.until today nothing has been received.This morning 18th December i called human motors kimberley again because my boot doesn't open at all and the funny noise in the engine since my car was for the 80000km service. The acting manager(Heine) said i must bring it so that they can check.At around 16h10 they called me to collect the car he said unfortunately the lock of my boot is a electronic fault they will not be able to repair it because I first have to do the 80 000km service and the lock of the boot is still under the warranty but he refuse to do it.my kilometers on my vehicle is only 78459km so how can he refuse.he said I I can just do what I want he is not scared at all for the consumer board or the ombudsmen he is dealing with them every day.he don't know how to treat his costumers at all.the way he was swearing and walk away it is unacceptable.
