Amazon India — GSTIN not mentioned on invoice

We have purchased HP Pavilion x360 Intel Core i7 on[protected] from amazon (Business Account) and that product sold by Appario Retail Private Limited. we registered our business account from Delhi address and shipping address was Uttar Pradesh. They mentioned both the address billing and shipping on Noida (U.P.) address.
we want to take input tax credit but we are unable to claim tax credit due to GSTIN not mentioned on invoice and we have called in amazon, we continuously talking for change but did not get any response and after that we have filed request for return this product but the days are passed no one come to pickup the product.
