Jaquar — water heater, 10l jaguar no repair since almost 1 month

Address: 605101

I ask for repair since 3, 5 weeks, called tollnumber 4-5 times.
2, 5 weeks someone from Tindivanam looked at the heater, he did not open, but somehow it worked, but next day it did not work again.
Since then, after many calls to the company Standard associates, where i bought it, a certain Kumeresan said he will order a spare part, one week ago.
Since then NO news.

3, 5 weeks !!!
Please resolve this case
