Bajaj instant water heater
Poor service at installation

I bought a bajaj water heater. The authorised person from bajaj company named Sunil came to install. He charged Rs 400 in total for installation which included Rs 150 for the pipes. The pipes started leaking when we used the geyser for the first time. Now Mr Sunil is least interested in mending his mistake and does not even care if we make a complaint to the company.
