hermanmunster, I notice your last negative review on here was two years ago.
If it was your rating or commentary on AW that got the response I would not do anything further. The weakness in the AW review system is that if you leave a neutral or negative commentary on AW the SP usually can, if they chose, leave a negative commentary in return. I have had various SP's accuse me of all sorts of atrocities in this circumstance, although mercifully in the context of a long series of positive AW reviews and comments. I have also been threatened the Police, Uglymugs, the International War Crimes Commission etc which all have about zero effect because I have not done anything wrong and the referenced body is usually completely uninterested/powerless anyway.
If it was commentary you gave on here that got the response I would be fairly relaxed, but you are generally well advised to keep your commentary anonymous make sure that SP's are not aware of or able to identify a link between your punting identity and your posting identity.
One further thing, on a couple of occasions I have had some success going back to an SP with a legitimate observation about bookings and services and getting concessions on subsequent bookings. I was able to establish a couple of successful regulars in this way and without them being aware that I write.
