[Resolved]  Sony India — Installation delayed by more than 6 days

We have purchased Sony X75H 55 inches brand new TV from bajaj electronics paradise circle on 15th August 2020. We have been promised by the shop that the TV will be installed by 17th August 2020. But when i called Sony on 17th evening they informed me that the dealer( Bajaj electronics) has not yet raised a request for the demo and installation. Immediately I had to raise the request and till date (21st August 2020) no one has contacted me for the demo and installation.
First how can the dealer be so irresponsible of not raising a request immediately after purchase. It seems they are only responsible for the sale of TV but not for the installation procedure since it is free.
Second how can a company like Sony not value its customers and treat them in such a way by delaying the installation for more than 5 days after raising a request. I never thought such would be the scenario of Sony. Now how can I be sure that Sony will immediately respond when there is any repair
