[Resolved]  Flipkart — gstin no. issue

I purchased honor 9n from flipkart (Order id od[protected] for my employee claims at bhel-hyderabad (Input tax credit) but the invoice which i received from flipkart and in this case, their sellers, health & happiness private limited, does have the gstin no.in it.
The website while buying is not allowing to enter gst information and after purchase also, there is no mechanism to reach seller/flipkart where they can take buyer's gst. I called customer care for help but they denied by saying they cannot help with this issue.

The contact details of the seller are not available on the internet, and flipkart's customer care has refused to provide me seller contact details. Not being able to claim input tax credit on gst during my employee claims at m/s. Bhel-hyderabad. Need flipkart to resolve the issue by including company's gst or take the product back (Which is just 2 days old).
