Yes, I can confirm they contacted me on Telegram and after a brief discussion BC.game decided to credit me the missing 88mbtc and paid me in full.
So, for me this case can finally be closed with a very positive outcome.

Thank you for all who supported me in this battle! I will now retract my support from the flag. I would like to ask everyone who supported my flag to retract the support too, although this is ofcourse up to everyone's own choice.
I'm glad BCgame decided to brush up their acts before it was too late to save their reputation. If I weren't limited in their sportsbetting, I would have considered to come back and play there but in this case I will just withdraw my funds now.
