HORRIBLY BAD service!!

I ordered some garments from Hey Something Sassy which had a size change policy if the garment ordered does not fit. I contacted them just after I received my order to change the size. They firstly took almost 2 weeks to get back to me, then they eventually sent me the new garment, which was the wrong item and the wrong size, they collected it and sent a new one which was the incorrect garment again. Now I can't get hold of them, and to this day, almost 2 months later I still don't have what was ordered. This is insanely ridiculous and freaking disappointing service!!
