Bought asus laptop from a store in dehradun and also bought a goodie on offer for which i paid rs.2499/- online. Bought my goodie (1-tb hard disk) from asus on 24th feb 2020.
The goodie arrived at my work place in dehradun on 26th july 2020, but due to the on going pandemic i had moved to my home town, so was unable to receive it. The courier end said that the product has been returned to the seller. But i did not receive any mail about it. Even after sending mails they did not turn up. Customer care is not picking up the call. I even asked them to deliver it to my new address but did not get any response.
My ticket no is: aic-030881.
I want to have a refund.
