You didn't have a chance to renew .. you had the whole season to renew. Not only do they put it in red letters at the top right of the screen .. they even tell you how many available seasons you have. This is totally on you. Not anyone else's fault.
If you send in a ticket, and if no one has yet been accepted, they will likely give you back your team.
WRT job qualifications, If your performance at that job is average or lower (and this could be because of a long term strategy that includes starting Freshman, etc) .. it makes sense that you were qualified when you took the job, but not after having it for a while. That said, I think the quals need to be more relaxed in general.
Your best bet is to put in a ticket and you might be able to get the job back. But don't blame WIS because you didn't renew.
