Last year on 2 occasions there were customer service issues, the GM of a Cat 8 property gave me the equivalent of a FN while the GM of a Cat 4 property gave me the equivalent of 2 FNs - I have NOT asked for any, nor even known that would be coming. I only saw the "bonus" as the description used by BonVoy, from the properties - in the case of Cat 8 property, I received email notification of the "bonus" from both the property and BonVoy...

I tend to agree it is more like the Marriott IT issues than the FD clerks trying to pull one on the OP.
