I'm amar deep gujral.
I bought a casio g shock watch on 25- march 2019, order no. [protected], costing rs 2000.
However the item received is a fake casio watch.
I had ordered a casio g-shock g345 gravity defier mens watch, and the received item is just a generic cheap plastic watch.
I spoke to the seller with mobile number [protected] who promised me a reverse pick up. Since then under various pretences, he is not taking my calls.
I just want a refund
