Vasanth & Co — Smart tv installation delayed

Dear sir/madam,
Good afternoon,
My name is hari i was buy SKYWORTH ANDROID TV 42 inches (sales invoice no :[protected]on 09.01.2021 at vasanth and co, avadi branch.
Today 12.01.2021 till now not installation.
I called yesterday day your branch manager, he said that company (SKYWORTH) installation boy leave for two days. When he come we send your home. Because we aren't responsible for installation delayed and service also. We responsible only for sales and delivery. You should wait for installation.
You buy over two days only. Many customers waiting for more than ten days. Because we sold out minimum 500 products per day. So we could not respond. So wait for your installation
Please give the solution at the earliest.

Thank you
Regards
A.Hari
