I also buying many things, and some times I also stucked with fake seller, very simply you must provide some video proofs and pics. So yo have many chances to get full refund or above 85%.
if Product is useless then you should marked it as not received and get 100% refund 
But please be sincere with good sellers and if you do same thing with them they ban Pakistan and next time no Pakistani can buy things from them.
