Ill let someone test it first, if no issues, ill give it a shot...
I've dealt with them some time back, to get WC3 Battlechest keys for one of my friends.When I purchased it, the RoC key worked fine, the FT key was disabled. Contacted them for a fresh FT key, they immediately refunded me the cost of the FT key. It wasn't the most ideal way to resolve it, since my friend still couldn't get on bnet then, but I guess it was better than doing nothing at all.As a result, I'm still not entirely convinced, but hopefully my problem isn't one that happens often...
