Billed on different time than was agreed

You know, you have billed me on the 20th for I don't know how long, and when I picked it up now, I actually came to realize that even AFTER I have mentioned (multiple times!!) that I only get paid the last day of the month, you still bill me and the debit order runs on the 20th. I am going to phone my bank now and have that transaction reversed, because you are \s t e a l i n g"my money as I did not agree with the same date that you are debiting me on.<br> <br> I really do wish that I could send you a snotty email and complain"
