Nagaon, Assam, 782123

Dear team,
Our geyser had an over voltage problem. We called up your head office in order to get the repairing. After 2-3 days two mechanic from the nearby city of tezpur
Had come for repairing it but due to lack of proper / new part they had taken the damage part (The heating coil) with them saying that they would repair it. But after several weeks of calling and remainders the service center in tezpur has failed to present the repaired geyser. On calling them (The main office) they would say that they are sending mechanics to bring back the product but still fail to come. So far it's been a month now of them taking the geyser part and not returning it. We have called them many times but they fail to provide a priper respond. It is being an very difficult time for us to live without it because of this cold winter. Please help
Regards,
