Charged for month's subscription. I cancelled same day and have no further access+no refund

Hello, 

I'm confused over Adobe's cancellation and billing policy and was wondering if anyone could help. I signed up to the Illustrator free trial, which I was unable to cancel the day it was up as "payment was due". So I kept it for a month further at the price of 30 quid a month, and then noticed the time had come for the second month's payment. I decided to cancel the day of payment as I had ended up in the same situation again of not cancelling early enough, and I presumed that, upon cancellation, the money would either be refunded or I would have access for the rest of the month and then it would lapse. I cancelled the same day I paid.

What has actually happened is the money went out of my account on 4th Jan, and Adobe took away my access from the moment I cancelled. There has been no mention of a refund. Have I just paid this company 30 quid for no product at all? It seems really unfair for them to not allow me the month they have just taken my money for, or else a refund of that money. Am I missing something? There appears to be no ability to phone or speak to anybody about this issue, as my paid membership and support was also cancelled immediately... Thanks for any guidance.
