Patience is the key here... It can very well take over a week to answer cause of the huge queue.
Friend 1 had 2 emercoin payment timeout problems on thursday 9 days ago and both problems got solved yesterday.
Friend 2 purchased 8TH/s on wednesday 29 nov. with wire transfer and as stated in the e-mail he had to confirm the purchase to them. The e-mail stated, it could very well take up to 7 days to get the hashrate.
While he was waiting for a reply, his hashrate got already activated 2 days after the wiretransfer but they still replied him 2 days ago to confirm the activation.

I'm pretty sure your problem will get solved to, fingers crossed
