worse site no customer service..

i brought 2 pair of shoes from snap deal and they send me wrong size and color both of them are useless for me and when i asked for a return i was old told that i will have to send them back myself instead of them picking it up as they say in their site that they will pick up the product by them selves even after calling the customer care again and again no solution was provided they are one of the worse online sellers beware people..
