I have much sympathy with your situation, and wish you good luck in finding a solution.
But if you are to do that, I suggest that you conduct your campain in an open light and with honesty and clarity.
1. The price rise you have suggested is 35%, not 135%.
2. While £2.28 is in the top 15% of prices as shown here

it's certainly not the most expensive around.
I'm not saying this to be smart or to nit pick with you, but rather to help you so that you can discuss the issues with those who can facilite a solution, rather than getting caught up in arguments with them over minor details.
Keep your argument clean and correct, and then you can keep it focused on the issues rather than getting side tracked.
