Poor service I got from this Gulf Techno AC Services Warasiguda, Hyderabad. The technician came and refilling the gas on my AC but after refilling also I getting the cooling Issue. Then he has done a gas refilling. For that, I paid 1300 for that. But they did not do the service, not in a proper manner still I am not getting cooling from the AC.So I contacted this service provider but they did not response me properly. Overall I received a bad service from them.
