My ex used to work at Barclays an she said they use to get loads of people (mainly single mothers) coming in to get they're bank charges reimbursed because they'd kick up a fuss that they couldn't afford to live an feed their kids. If you go into your bank an ask to speak to someone, explain that you can't actually afford these charges an you won't be able to eat etc. then I'm pretty sure they have to do something about it.
