Sony India — motherboard has conked

Address:

831005

We have bought a sony led 32 iches tv on 21.10.2017. On saturday that is 5th of october 2018 the tv suddenly switched off on it own. I immediately logged complain with sony service center. My service request id is 50384172. Technician has visited on 6th of october at 4.30 pm and told us that the motherboard has conked. He told that he would be done on monday. Today i called up technician he says that the it would take 5 more days to put the motherboard as it is not available in the stock. This is not done as i feel because sony being such a big brand the parts should always be available. Please do something so that it is done in next one day.
