It doesn't sound like the data you describing would have met our automated data deletion policy criteria.
We can see the metadata of maps that have been deleted in your account and don't see anything that matches that description.
There are a few deleted missions in your account but they are free ones from last week and one labeled test from August. The ones from last week would have had to have been deleted using the "Delete Map" button at the bottom of the Map Detail page.
As long as a map is paid for by pay-as-you-go points and is actively being viewed it won't be deleted. If it was created while you are on a subscription it will be kept until after your account is no longer active.
