Shawn acd gezina

I bought a opel Astra with a blown head gasket I paid Shawn the owner of acd gezina brach R5000 to do the head... After 2 weeks got my car back after 2 days relised it's still mixing water and oil. He said bring it back they didn't flush it... I pay R5000 and they didn't flush it I mean really... So it spend another 4 days there I got it back and after 1 day relised it's worst... I took it back again.... This time for 3 weeks got it back and it worst... It's now at another mechanic with showed me that no work was done one the car at all...when I call him he swears me calls my mother a ***** who he doesn't even know.... Pls people stay away from this garage don't want him to catch anybody else
