No vacations due.

So you want to contact us. That's OK.

We have phones but generally don't use 'm. Or we are on the phone already. Not a good idea.
We have a forum but maybe you don't like to use that. 
We have sales phasure com for email. Yes, that would work. But if you feel you like to go the formal way, then here's our contact page. Results in that email just the same but slightly less convenient. Or more distant perhaps.
