Dealercostaudio has horrible service and i consider them a scam site, they take your money and never ship the products. I had a huge problem with them and so did 2 other guys i know. I learned my lesson dealing with them, never again!! //content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif//content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif
OP i am not sure why you would wait 11 months for them to send you products, you should have gotten a refund after the first few months and purchased the product from another shop. I am very sorry to tell you but i think you have been scammed and at 11 months after the transaction you can not really do much either through your CC company
