Very poor service and poor Client service

I took my vehicle to repair an oil leak. The owner said to me this is the Cam belt pulley seal and say to me that the oil filter also leaking oil and I must replace this also. After he finish with my vehicle my oil leak was worst ad before. He never answer his phone and I took it back the next morning and he was not there. His Mechanic told me that he will look for me to see what is wrong. I took that seal he put in for me to a spare shop to get a new seal. This people laugh at me and told me this is a bearing seal and not a Cam seal that this person put in my car. It cost me to pay someone to take me to the dealer to get the right seal. He charge me R 50 for that wrong seal and the real price is R 8.00
