work not gaurenteed

Started last year abouy August2014 i took my white polo for a manufolg gasget repair at lombards an Jr helped me then informed me that my old manufold is uneven i then got a manufold from him and lombards fit it with a new gasget. In Jan 2015 to the end i took it back because it starts to leak again and i had to fight for them to fix it again and it lasted a week. I went back and spoke to Jaco and he said they cant really helped me because the manufold i bought from Jr is also uneven. After a fight again Jaco helped me and they say that they have send the part for skimming. Ive got the car back and Jaco said they cant help me any more because there is something wrong with my cars engine thats why the manufold are leaking. Now i sit with a laod noisy car because there fitment is very poor and do not know if they did what they have said. I went to another place and they quoted me over a 1000 to strip of manufold and fit gasget again which i cannot afford and want to sell the car but now i cannot. The part they took of last year they never showed it to me nor hand it to me back so i wonder if they even changed it and now the Jr person is not working there anymore so its easy to say no
