O2 TV and Sky Ticket

Hello, 

I had subscribed to Sky Ticket through O2 but I cancelled it online owing to a bad user experience. 
That said, I didn’t get any email or SMS informing me that my Sky Ticket has been cancelled, except that ‘abbestellt zum 16.12.2019’ appears next to it on the website. I would like to know that my Sky Ticket has been cancelled - if not, i would like to cancel it as soon as possible. 

Additionally, I hadn’t subscribed to O2 TV but was automatically enrolled into it. I cancelled that too but didn’t receive any communication. 

I would like to know the status of both, and if they haven’t been cancelled, I’d like to terminate them with immediate effect.
