Not having enough time to read all 5 pages, I limited myself to the first and last, thus only read posts 1-40 and 161-186.
Welcoming constructive suggestions in my own back yard, I do occasionally give suggestions on improving functionality when checking out of a hotel. This is easily done in the private conversation with front desk associate. Less frequently, I might hand over a small list to the same person, and only once around every 5 years, the problems are of a magnitude to request a talk with the MoD.
Publicly shaming an establishment on social media with pics and words, and doing it so regularly as to achieve the amount of compensation mentioned here, does sound more like a business idea. I join other posters who question why you keep coming back to a hotel family that never satisfies your demands?
From the posts I've read, the reasons for closing the account on the "pooling" of points isn't obvious. Sorry if it is in the 120 posts I did not read. There might, however, be more than one reason for breaking T&Cs. Maybe in the other tens of e-mails there are more information than displayed here?
Move on to another hotel room provider. Good luck in finding anyone fault-free.
