for my mobile plan, I am try to apply well earned bonus (upgrade), but I get this weird message that does not make sense to me.
Anyone has an idea?
I assume that your system clock is not off by a few years.
This looks like a technical fault that needs a bug report via the contact '?' links.
i contacted support and they escalated the issue.
it may be because i just reactivated a plan which i disconnected back in 2019. Anyway that's a bug.
similar outdated messages appear when trying to adjust the plan or trying to buy add on
Before you get it fixed, you should see if there are any useful features that you can grandfather in before.
Who knows, maybe their prices will be from 2019 too.
