I purchased new gas connection from shree raksha gas agency.They charged full amount and provided damaged gas burner with different company warranty card inside the the packet.The delivery boys charged extra 180 rs for installation and had not tell us the burner pipe had broken. When I talked to customer care they helped me and told me that mechanic would come in 30 mins.This is the case of blast because we don't have any idear about pipe had broken.The mechanic as well as the delivery boy checked the gas but they didn't tell the issue to us.After my complain number registered.I got call from.mechanic and after 2nd esclation, same mechanic calls me tell me, I will not come.You will come to office tomorrow.The same mechanic is asking for 160/150 rs.Why should I again pay even at the very first day of installation? So much corruption in this agency...new gas stove named surya with warranty card of Kohinoor netanis.This gas stove is packed and is opened by delivery boy infront of me.Mechanic name is Jagdeesh.
