xheli.com FAULTY USED PARTS el monte, California

www.xheli.com is selling used pcb boards (the green things with sotter on em). i orderd two of them  one for my double horse 9100 and one for my double horse 9116. both had very poor soldering joints on them. one of them would not even bind to my transmitter,and the other,after installing it..i took flight and when i went to throttle it down,it jus kept going and going. it wood not respond to the controller. and it ended up smashing into my garage. my canopy and main blade grip were destroyed as well as my tail motor would not work anymore. i called xheli on like three different occasions with my complaint but all they would agree to do is to send me "new" pcb boards.  i told them that i was very upset that i recieved used boards and that i was unaware of said parts being used,they told me that no where on ther site does it say that the parts are new!! i also told them that i feel its only right that they replace my damaged parts (canopy,tail motor,main blade grip)..because its on account of ther USED! pcb board, my heli is severly damaged,they then told me that they cant help me and that they wood only send me a new (USED) BOARD. i was ripped off and its not right!!!
