Hello Forte42 and welcome to DS.
As a general comment, I'm sure the production team want you to mention and write down every room 'defect' you find as you examine a room but do they (try to) force you to mark down or underpay? Do they tell you to pull out the bed to look at the wall? If so, could you have said no? Criticising small marks or missing paint on skirting boards is really absurd and just makes the competitor look petty.
However, I've just re-read your post above and see that you said:

If I understand you correctly, the production team applied pressure to persuade you to say NO you would not go back... is that what happened?
If you have time (and inclination

) to say, I'd be interested to know:
Had you seen Four in a Bed before you went on it and did you understand how a property (and its owners) might be misrepresented?
Do you feel you - and the other participants during your week - were represented fairly or did you think that the edited version was biased in any way?
Do all owners choose which guest goes into which room or do the production team have any say in that decision?
Now that you have been on Four in a Bed and you have seen 'your' week, do you think you made the right decision to appear?
