Toyota – about their worst service and unprofessional staff

I took my car for servicing Toyota being unprofessional didn't do the proper service, the basic thing they missed out on was to check the gas due to which AC was not cooling properly. I take my car again asking them to check the AC and its only about gas refilling which should not take more 20 minutes. But their unprofessional staff wanted to keep my car for the whole day for a 20 minutes job. Giving me excuse of having only one technician in the such big service center. They were very unprofessional, arrogant staff no body was ready to help. Worst service provider ever never going to recommend or get any service from Toyota ever. Useless service provider, all they know is how to fool their customers, charge them for no reason and disappoint their customers with their useless service and staff.
