Go Mechanic — ac gas leakage

I was working in c. P, so due to lack of time i went online for my car service and gave my car to go mechanic, as my car ac was not working i told the person to check and tell me the problem, he called me and said that ac coil is leaking that's why ac is not working, i told him to to fix a new coil and he gave me car back... After two days car ac stopped working, i called him he said bring the car will check again, i went all the way to vikaspuri delhi to hs work place, where he said the problem is different, so i told him that i will get it checked in company.. As summer was over and lack of time, i gave the car after two month and told the company to check ac too they told me that cooling coil is leak and it was never replaced... As my budget was not there so i told them not to do and i called the go mechanic, firstly they refused to take the case as it was two month already and then they again said we will check,, but after so much i was frusted and decided in this summer to get it done by a known friend in karol bagh, he gave me video showing that it was never replaced... So i whats-app go mechanic the same video for a action but they never bother to even call me and take some action, i told them i will complain in consumer forum they told do it... So i am here seeking a hepl against such people and tell them if they do wrong, they have to pay back double... So that do not cheat any one in life.
