Products not as advertised and buyer need to pay for there mistakes :-(

Very bad service, I ordered a co2 pistol, it was advertised as blowback, when I received the item it was not as advertised, it was non blowback, with a fixed slide and not even the hammer could move. I told them and the reaction was send it back if you don't like it. Well I did, and they do not even want to refund my shipping costs. They sold items not as advertised but the buyer is expected to ship there faults up and down. Do not recommend this shop at all. STAY AWAY if you buy online from them!!!
