The terms of a contract (or in this case, T&Cs) should be clear and unambiguous so that both parties understand their rights and obligations. If a term is open to interpretation or could be understood in different ways, it may lead to disputes or disagreements between the parties.
This is what happens if terms simply "imply" something versus being clear and exact.
The fact that a reserved redemption stay in the future does not have a in app signifying it is not a qualifying activity or even data points in this forum suggesting or even confirming that only a completed stay will yield qualifying activity does not matter, because there is a written T&C that exists and you cannot go beyond the 4 corners of that document.

There have been events in multiple loyalty programs of which I have had a part to play by raising issues that actually got T&Cs changed (e.g EMEA element hotel free breakfast offerings). So believe it that these staff can be wrong.
So, no I'm not playing the victim, nor do I want to be a victim. I just want these loyalty programs to either follow their own T&Cs or hire a better legal team.
