SIR

I had ordered 5 koutons shirts on 16/02/2014 through online shopping form company 100bestbuy.com.I recived my order on 27/02/2014 by cash on delivery basis.So i paid money to that executive and got the order in my hand.But when i saw my order that is my shirt, it was totally damaged and so dirty.
Than i called on company customer care number then they said that by mistake i have got the defective peace and i should return that order, so i will get a new order ie good shirts as they promished on site.
I done the same thing and returend that order on 04/03/2014 but till date i havent received my order, then i tried to contact to the customer care, they are just putting my call on long hold or just disconnects my call. I cant understand what to do.
