New update from Valve: http://www.dota2.com/news/updates/40646/
In this update, Valve removed MMR bonus from Team Challenge tokens and make this kind of tokens useless to gain party MMR. It affects Viking Team Challenge service: www.vikingdota.com/teamchallenge
For all customers who ordered our Team Challenge service before this update, we will still boost enough MMR in your account as your order. It means that if you ordered 5 tokens, you will surely get ~600 MMR boosted after order is completed.
All customers can keep track of order status and results on our Order Tracking page: www.vikingdota.com/tracking
Thanks & Regards,
