Car Care Clinic in Nic Diederichs Wilgeheuwel****tle Falls) I WANT MY CAR BACK WORKING!!!! ******* SERVICE!!!!!

I took my car for a major service and checks at Car Care Clinic in Nic Diederichs Wilgeheuwel****tle Falls) November 2018 and I was charged r6693.95 for major service,engine flush, fuel pump etc including r200.00 fuel (the car came back empty), they told me the car was ready for collection in November. It was collected, i went to the petrol station to fill it up but the gauge didn't move at all. in 2 days it was the service light was flashing - I phoned them they asked me to drop it off again, I paid the tow guys for the second time. dropped it off and after a week of waiting with no feedback I phoned and they said they cant help me. Like *** after almost r7000 payment I learned the service was not done, I bought a battery for r1000 as it couldn't start anymore and now its been two week that they've had the car and nothing done. I want my money back!! what a ****ty service I had and the tow company only warned me after I made a payment
