I understand that you feel cheated by the airline because you had expenses for services you finally could not use. It is understandable that you are not happy with the responses you are getting. But no need to shoot the messengers.
EC261/2004 would cover any extra expenses you had to endure because of flight delays due to cancellation (duty of care), But we have never heard that the airline would reimburse you for services you could not use. Sorry..
