V-Guard Industries — V Guard Stabilizer

I purchased a V Guard Stabilizer about 2 years ago on 23rd Feb 2020
Model - VGMW 800 Plus
Input Voltage - 100 V - 300 V AC
Output Voltage - 200 V - 250 V AC
Capacity - 25 Amps

This was working fine this date and suddenly towards March end. The Stabilizer stopped working

I raised a complain 1-[protected] on March 28th
Firstly - your team was supposed to visit within 48 hours - DID NOT HAPPEN
After 3-4 days you technician comes and says that the Fuse needs to be changed and will takes a 3-4 days to return this.

After a 3-4 days, you technicians calls up and says that the transformer is burnt and since this is out of warranty, i will have to shell out 10000 Rupees.

Now please explain this to me...
A - This is a stabilizer and is supposed to control voltage fluctuations
B- This is meant to stabilize the flow of current, in other words, this is meant to bring high voltage down and also boost the voltage if the electricity current is low.

So how can the TRANSFORMER BURN ...Please explain this to me.

Secondly just a month has passed (since the expiry of the warranty), could you please look into this suggest how we can get this repaired without any additional cost please.

Appreciate your support here
