TrackChecker

Brazil Post has the following problem.
When a package is delivered, the message from tracking will say "entregue" (delivered). But if there's any problem and the package couldn't be delivered, the message will tell "não entregue" (not delivered).
The problem is that the word "delivered" (entregue) is being interpreted alone without the "not" (não) in "not delivered" (não entregue). So, in this case, instead of keep tracking on, the app will consider the package delivered.
The solution consists on creating a condition of not having the full expression "not delivered" in the tracking information to consider the package delivered, or to use the full expression of delivery to consider the package really delivered, that is "objeto entregue" (object delivered) instead of just the word alone.
