D'uh!
Bloody naughty to disable active, paid for, deployments in retaliation for open criticism. That crap about it being impossible to say how many were "wrongful" deactivations, as some or many may have been genuine cancellations and refunds. Surely you have records of those cancellations and refunds? Your accountant would insist on that, surely? Then you take the number of cancellations and refunds from the total number of deactivations over the same period and you have your wrongful number of deactivations. Your accountant could probably explain that to you, too.
