I have ordered speria 6.3 inch mobile and paid through payu rs. 3999/- a company named gadgets and watches, of mundka industrial area new delhi-110081 sent a mobile through blue dart currier. When opened i was surprised to see that one old mobile in the name of spiria and that too not working. One useless adopter only included in the package.
The package had one number [protected]. I tried my best to contact but no response from the given number.
The company sent the delivery on 10 aug 2019 and i received on 15 aug 2019.
Any way how to get the money back or get the original mobile.
