Videocon Industries — Videocon Refrigerator Delay in Service

My Videocon Refrigerator service request ( LP[protected] is open for the past 2 months. The request for service was raised on 15/06/2022. The engineer came to visit on the same day, checked the refrigerator for replacements and told us that he will visit again with parts after 2-3 days. It's going to be two months now and his 2-3 days are still not over. I have been trying to get the progress from customer care but all i get from them is that they have escalated my complaint to higher authority. They even didn't have given me the complaint number on text or mail saying that they are not authorised to send me the complaint details and if i want i can write down the complaint number and proceed on my own with that.
