Zerolag has been a friendly partner for us, but recently with one client in particular, we had issues that required more inquiry and support tickets to be opened. Most responses were incomplete. We haven't had any issues setting up.
We offered solution ideas to some inquires and received incomplete responses that ended up costing us an entire day for each back and forth.
As an example:
We submitted a ticket saying, "the firewall is blocking our IP. Please whitelist xxx.xxx.x.x"
The response was, "We shouldn't be blocking your IP."
We already knew the IP was being blocked. We were looking for a solution to the issue.
After confirming the IP was in fact being blocked, the response was that one of five was whitelisted with a question of whether we wanted the other four whitelisted as well. Since we wanted them all unblocked, this should have been common sense, but required another back and forth to confirm.
