In 2012 I had issues with a Tribulant plugin. It routinely took Tribulant over 48 hours to respond to any support ticket.
In 2017 I had issues with a Tribulant plugin not working as advertised, support ticket waited over 48 hours for first response; I'm still waiting (over 48 hours) for next response. Tribulant is only good for people who will never need tech support from them. Tribulant does not provide timely tech support.
It routinely takes over 48 hours for every response from Tribulant tech support. I sure hope that your clients don't mind waiting a week for their website to work properly.
Reason of review: Poor customer service.
Monetary Loss: $1000.
Preferred solution: Let the company propose a solution.
I didn't like: Tech support that takes days to respond.
