Cannot submit address change without consenting to marketing communications

As part of the process to submit a request to move my services to a new address, I was presented with this check-box at the bottom of the form. This is not a box to indicate reading or agreeing to any terms or conditions, it is simply a box to say "Yes, I would like to receive more spam emails from you." In every case that there is a check-box like this on a form it is always optional. However, in this case it was NOT optional. It was required to click on it in order to submit the form. That's just wrong. Yes, it does say you can "withdraw your consent... at any time," but I shouldn't have to be forced to give "consent" in the first place to submit a required form.
