Debit cancelation refused

I signed up for the promo 2gig mobile data where a sim is delivered to you.<br> My reason for signing up was to test the data and speed of Axxess so I gave the go ahead for the debit order for Jan.<br> Today I get an email saying that I have to pay the end of Feb for another month, I was under the impression there are no contracts and that you buy as you need data not automatically get debited from your account I didn't ok this.<br> I immediately emailed to cancel the debit order and Anika Wilson said I can't cancel the debit order it needed to be done before today, how the heck can you email me the day it has be cancelled and say its too late the debit orders are loaded. I feel like you're *****ing my money and I didn't budget for this.
