I can confirm that Cryptoadviser isn't lying, he did pay me back 1btc for my yins.
so he paid you back 1 BTC but he doesnt want to pay me back 1.2 BTC for original ICO investment...?

He is talking about the yin/yang swap that happened a couple months ago. Not the hmy refund that didn't even begin yet.
And noone is going to get what they invested back in full.
