Hi,
I faced same issue sometime back when my bought tokens from hitbtc got disappeared and HITBTC support people replied that they cant return money.
Few days after above incident i lost my login as i could not use my 2FA authentication and support people not replying for my ticket raised for resetting my 2 FA. Since then i am not able to login to my account for accessing my remaining tokens. HITBTC support people do not care of this incident.
These guys seems to be scam and fraud.
