We're sorry if you're seeing the 'Account locked' status, but hopefully the advice here will get you get up and running again.
1. The thing to do here is contact your Timetastic account admin user, it's probably your manager or Director.
It's a relatively easy thing to sort, most probably the payment card has expired a month or so ago and they'll need to login and update with new payment details.
2. If you are still just trialing Timetastic then chances are your trial has expired. If you need more time then that's fine, just reach out to our support team email@example.com and they'll extend it for you.
