Hi, everyone here

Sorry if i had posted a thread in a wrong section. Hope there are some veteran here could lend a hand in this matter.
I would like to know that anyone here experience similar situation here where losing the Ti 2013 battle bonus after a few match of Co-op match for Dota 2 after September patch ? Is there anyway to claim the battle bonus back? And lastly which place should i really seek for help in this case?

Thank you very much
