Bad service and ****

You know what... I thought taking my back to its dealer its the best dicision of my life .. guess what I was absolutely wrong ... I took my car there coz it idleing was not smooth.... and I did my major service with them and asked them to check the idleing as well.... They haven't even bother to check what is wrong... or at least do daigonosis on the car ...they only said someone else has worked on the egen and i must take it back to those people.... And guess what... One of their egenering approached me offer to help me his name is Rafic Kamaldien little did i know that he is going to **** me... He said he will but the sensor for me...and i send him the Money and now he is no where to be found....I dont trust DTM Renualt in Strand including its employees...they employed ****mers....
