GS Techno Service in Hyderabad has reviewed by Pooja kapur
April, 11th 2016It is very unfortunate that your services are very unprofessional. I have to call up in number of times, every time to get my complaint lodged. Your service men do not pick up the phone. They cut our calls. I waited for the entire day to get my filter serviced and no one came. This has happened in number of times.
