Sunflame Enterprises — electric water heater grace 25

We purchased grace 25 liter electric water heater (Product code iggoj25ch[protected]) from gambhir son's, 2 the mall road nahan, district sirmour, himachal pradesh.
I am forced to inform you that even after multiple phone calls to customer care number given[protected],[protected] in the back side of booklet no reply received. I hope this number is not valid. The purchased water heater is not heating the water at all since the day we purchased.

You are requested to please send some to rectify the problem or replace the same urgently.

Regards,
