Bosch Home India — Freezer Fridge

I have purchased fridge from Bosch last year Nov 21. Since last 2-3 weeks it has stopped working properly and lot of water droplets can be seen inside fridge, things are keeping fresh and getting rotten up. Even after raising complaints with customer care multiple time no one even bothered to appear.
I even got number of area manager MR. Dev but he is not in a mood to pick calls whole day 365 days in a year.
Assist in getting my complaints resolved. I am having a very bad experience post sale service with Bosch
