There is an ICO head office where you can make complaints
I thought this was legit but you are talking with a different meaning for ICO. As for DooMAD, you're giving a wrong service to OP.
ICO's are decentralized and there's no head office or governing agency that is regulating this if someone has a complain and this is why everyone must be careful of investing on it.
That's right ... but i have seen that there are ICO escrow companies. I havent looked into how extensive they are, but the idea seems legit. If they are credible enough a company like that, can be your seal of quality assurance.
