Thank you all for taking the time to reply. I did eventually get an answer from changer.com
The whole issue took about a week to resolve, but at least Changer.com refunded the money. It seems the issue is on Bytecoin side. Their 3rd party app for windows does not sync well. I waited 3 full days and got only to 33%. I read from other users on the net that they never go past a certain height in a block. But worst of all to me. I sent several emails and Bytecoin NEVER replied. seems other users have the same problem. My advice... Stay away from Bytecoin.
At least thanks to Changer.com fpr doing the refund.
Conclusion: Changer.com is safe to trade with
