Junkcard.com Scam, fraud Internet

 Junkcard is listed as a website where you can buy giftcards and sell unwanted ones. I wanted to sell my giftcard (they send you a check at about 90% value). Per instructions, I mailed my giftcard of $700 and got an email dtating that the check has been amiled and should areive in 5-10 days. One month later and numerous attempts to contact the sales rep, I still have not recieved my check. Thank God I wrote down the giftcard number before mailing it. I was able to use it on online purchases. Stay clear of JunkCard.com. Its a fraud. There is no phone number to call; only email to which you will not get an answer.
