Non-delivery of essential goods

I ordered a laptop for my child to do school work on the 8th of May. I kinda expected a quick delivery because Laptops are declared essential for studying since April during the lockdown. The initial Estimated Delivery Date was the 22nd of May. On the 19th of May I got Delay Notification which extended the Estimated Delivery Date to the 29th of May. As if that is not enough, on the 22nd May I get another Delay Notification Date that extends the Estimated Delivery Date to the 5th of June. I wouldn't be surprised to get another Delay Notification. I have two undelivered orders from them and am not even concerned about the other one yet because its not essential goods. I have seen a lot of unresponded complaints here and on other platforms, and that just drained my energy. It's ridiculous how they don't give a damn, just enough, to at least respond to enquiries or even refund us so that we can buy elsewhere.
