Remember, You the Bounty Program participating people, are in the right; hence, you command the moral high ground here. You should complain to the House of Lords, and to Buckingham Palace that someone associated with them, and flaunting their association with them for professional gain, is behaving in a manner unbecoming of that stature, and has brought scandal and disrepute to their august establishment.
The British Royal Family and the House of Lords are all about dignity and high honour. Cheating poor unpaid daily wage-labourers in third world countries is a scandalous proposition to them. It's about as acceptable to them as loudly blowing one's wet stuffy, mucoid nose into tissue while on-stage at an official function.
You can also contact media like the Sun, Guardian, Times, Telegraph, etc. Here's some nice authoritative coverage on this story, that you can share with the other newspapers.

You will have to draft and post a petition for rescinding her Baroness title, on change.org. With your masses of unpaid bounty campaign members, and their PR experience, you shouldn't have any difficulty in getting the high numbers on that petition. And lots of news coverage of your plight in addition.
Just my $ 0.02. Hope it results in some concrete results for all the Bounty participants who seem to be unfairly dealt with here.
