Hi all, I've recently been charges 2 x £25 for a failed standing order and a failed direct debit. To tell me about this they've sent me a single letter. This seems like an exorbitant amount (I know they're a bank, but still). Is there anyway I can challenge this with a likelihood of success? Given that the whole process is automated, for a letter, I'd expect a charge of, say, five pounds. Any advice very gratefully received. Thanks, Mark
