Jaquar — Water Heater - Not working

I bought Jaquar water heater of 10 Litres. From the day one it is having problem even after repeated complaints, problem was not resolved.

Problem - Once it heated to the maximum, it will not heat further. Every time the technician will come and enable the fuse inside the heater and will start heat, but again only once it will work.

So I reached Jaquar support for the replacement, they said based on the analysis of the problem they will update me on the replacement or will be repaired. They have taken my heater on 22 Jul 2021. Till today(21st Sep 2021) I didn't receive my heater back.

On 24th Aug 2021, I called up the technical support of Ernakulam branch on and they are telling that they have to replace some component in the heater. Again there is no response.

On 02nd Sep 2021, I called up again the support through which the call was escalated to Ernakulam branch, Sridhar from that branch said, I will get a response within 24 hours. Next day, I received a call from Service center stating that they are checking the issue. Again no response.

On 21st Sep 2021, I called up again the support again escalated to Ernakulam branch, now they are telling it will take one more week.

I received a faulty product from the Jaquar. So I need a replacement, but don't know how to proceed.
