Thank you for contacting them 
I think I can understand them somehow.
The real big problem here seems to be HitBTC. Many told me that they invested, because the token was already listed. A listing on an exchange can be definitely seen as some kind of endorsement. I talked to some ICO entrepreneurs and they told me that you just have to pay HitBTC the right amount of money, then they list everything.
In these days money is important for them to list any ICO either they were scam or semi scam etc. I am seeing everyday a lot of ICO's exchangers just like PTC programs. People need to research or read this forums before investing and I also promoted Coinlancer, still not yet known who is the developer.I think I can understand them somehow.

I really do not know how you could have promoted them. This was the most obvious scam since a long time.
I think you should be really ashamed to have promoted them!!!
