Created account, wrote down all neccessary information for security. Everything worked fine even logged out and logged back in no problem. Problems only have after i added btc, they needed my pin and i was entering it but it was coming up wrong so i logged out to see if that would fix it but while trying to get back in it told me that either my password or account was wrong, i made a new account and made a ticket but BigMuscle just closed my ticket without a response. In my ticket i put my username, my pin, my mmenonic sentence, and both the receving and sending addresses of the btc transfer and no response. i had close too 300$ in my account
Sounds like you got phished.
