pinupgirl clothing has the worst "customer service" and ripped me off monrovia, California

I ordered 3 items from pinupgirlclothing and only received 2, i was charged for an item that was not in stock and therefore not shipped to me and had to contact them for a refund. I checked my bank statement days later only to find i was only refunded $19 for a $23 dress..
the second item i returned for a different size which has yet to come...i mean it's only been two months right?!
after contacting them repeatedly by email, once by phone (left a message which wasn't returned) and using the live chat thing (two weeks ago) was told it would be investigated and i would be emailed (insert crickets chirping) so i'm still out $44 dollars...my next step is to call my bank and see if they can help me out because they have once before in a similar situation (thanks USAA!)
there's a good reason why they have a horrible rating with the BBB come to find out

their "customer support" sucks and i'll never buy anything from them again and i intend on telling my friends not to also via Facebook so the word gets around!
