Looks like my M&M number has changed. They have now given me another number. My original number is on my HH profile.
My most recent stay of a couple of weeks ago credited on the invoice but has not appeared on my M&M account.
The reason for my questioning is I went to book a car with Blacklane and they said my M&M number was wrong.
So not sure if I have lost that 2,500 points or whether they will come through.
All very odd....
