Kent Kruger - K Tech owner takes your money and doesn't do the work after 15 months

How do you put MINUS stars on the rating?? We took my husband's car to Kent Kruger, owner of K Tech in Roodepoort, to have the engine redone in NOVEMBER 2018. The car is still not fixed. He was paid in full upfront so he already has him money. In November 2019 (yes, a WHOLE YEAR after having the car in his possession) he returned the car, claiming to have fixed it. The car drove for about 25kms after cutting off next to the highway and has been standing ever since. It has taken him 15 months to try and fix this car. Phone call on top of phone call. Sms's and whatsapp's have been sent, and this guy literally couldn't care less. We have spoken to him nicely. We have pleaded with him. We have fought with him. And it has gotten us nowhere. Promises are being made at least 5 times a week by him that the car will be fixed and on a Friday afternoon at about 3pm, he switches his phones off and/or blocks our numbers. On Monday morning his phones are on again and we have to listen to him spewing nonsense about why he was, yet again, unable to fix the car... AGAIN!!! I have had it with this guy!!!
