Totally fed up!!!

I don't know why Miway even call themselves Miway or is it because they do things their way and not the clients way. I have asked them to keep to the agreed debit date which is the 24th of every month but yet they still debit on the 23rd. Today it is the 19th and they have debited without giving me a notice. I am really getting sick and tired of Miwy, better find myself a lifecover with a company that will do things Miway since i am paying them to do so. I am really fed up with the level of incompetence from Miway, what's difficult about just changing dates i wonder if something God forbid happens, is this the kind of service my loved ones are going to get?
