1 user messages Zen of of hours on a Sunday afternoon and gets a response within an hour.
Another user messages on the Thursday before that, during working hours. They took till Tuesday to answer.
Some would think Thursday to Tuesday is a good enough response time. My thoughts are why ignore 1 ticket for 5 days but answer another within the hour.
If the Thursday ticket was more complex then respond saying we need to look in to that.
I think there's an issue with how Zen queue tickets. My last few tickets went completely unanswered (granted it was a while ago now) so I left. No idea if tickets just get lost or if agents read them and just don't respond, leaving a ticket in limbo.
I was with Zen specifically for email/ticket/text based support and they fell short imo.
