Tata Motors — Extended warranty and quality of Nexon

I have bought Tata mein I'm 2019 . Have took extended warranty. In 2021 April I got kovid and than black fungus twice. Was admitted in hospital for almost 60 days. During this illness I missed to give car for service. Now my car steering shaft got problem in just 2.5 half years and 25000 km run. The service center said that the warranty is void as I didn't give my car for service on time. This is really scary a company which boast it's ethics in business serves it's customer this way. The quality of car is disappointing and now I lost the money I paid for extended warranty as well.
