I have tried on multiple occasions to get the Guaranteed Welcome Gift honored in person. I check in, nothing is offered/status not mentioned (I'm Titanium) and I then ask for the compensation after checking in (note I did not check in online which automatically selects points) and spend 5-15 minutes explaining the T&C's to the front desk agent. The front desk agent says something like "I don't know about that, you were automatically given points and I can't/won't/don't know how to credit you." I ask for a manager and they aren't in. Before checking out I go through the whole rigamarole again with another person at the front desk with the same answers and the manager isn't there.

This happens A LOT.

I then call to make a complaint on the "Titanium service line" and file a complaint. It's ignored. The last several complaints I have heard nothing back.

It just wastes my time every time and I get nothing. Should I just give up trying to get the money the T&C's promise and assume that this is just a Marriott scam?
