They are all bots.
Hahahahaha
I'm pretty sure there's no bot behind the eXch Support account, at least based on some of the various discussions here. Judging by this reaction, it seems @Synchronice got a reply to the PM here after 40 minutes, which can be considered relatively fast for a non-automated reply.
Can we solve it here via PM or is it better to contact them via email? Also, is their support good? Do they answer quickly? (Service is good).
