What exactly is the main objective of your post? You deposited your funds into Rollbits, go a notification to contact support, and after contacting them you got your funds and withdrew your money back without any other issues.

This thread would have been more appropriate if perhaps you were unable to get your funds or were asked to go through some complex process like being asked to submit your personal information that you never planned to do in other to get your funds back. But fortunately, nothing like that happened.
