I've recently read a number of posts regarding 50% bonus points being due when such things as the diamond amenity points or the bonus points for club lounge closure are not automatically posted, requiring a request to be submitted to GP.

My question is if bonus points are supposed to be awarded when points are credited for a stay but are well short of the correct number of base points.

One hotel I stay at frequently consistently shortchanges me on base points. For the most recent stay I contacted GP and found that the hotel has recorded more than 1/3 of the total spend as ineligible; tax is 5% and there's a 10% service charge, but everything else was room and room service food (no alcohol). GP told me there was nothing they could do, so I contacted the hotel directly, and they admitted that the points credited were too few and said they would contact GP to have it corrected. No offer of any compensation for the trouble of 3 emails to GP and one phone call to the hotel.

Over the past 2 years this has happened at least a dozen times at this same property. I'm usually not that diligent in checking that base points are correctly calculated, but all by stays at this property are just one night, so while the shortage is not that large, it is also very noticeable. With charges for taxes, service, and sometimes alcohol excluded and differences in the exchange rates used, it is painstaking to figure out whether a base point credit of 10,000 points is short by 300 points, but it is pretty obvious when only 500 points are credited instead of 800.
