Howdy, Alexey!
Well, I'd say there isn't a protocol (or an interface
) to follow in such situation... what you can do is wait until, say, thursday and see if things change... if nothing changes, then you can send an email and explain your situation. But, once you received their email, then there is nothing to worry about.
