tl;dr - is requiring people to call up to cancel a free trial bought online legal (from both a disability discrimination point of view, and also a consumer rights point of view)? If not, who can I report it to?

I read a lot of online news and after seeing a few Telegraph articles that looked interesting, I thought I'd sign up for a free trial

After reading a couple of articles I decided that I had no interest in continuing the subscription - sure the articles are better than the drivel that Reach plc (Birmingham Live, Coventry Live etc) tries to pass off as journalism, but they're nothing special and I wouldn't personally say that the subscription is worth £14.99 per month

I go to my account page to try and cancel, and I'm met with a message saying I have to call up to cancel - no option available to do it online. A quick Google search suggests that if you do try to cancel on the phone, you're met with 20 minutes of aggressive sales pitches before you are finally let off the hook

I opt to email [email protected] letting them know of my intent to cancel, explaining that phone calls are difficult for me due to a disability, and provide my account number. Within minutes I receive a boilerplate response saying that it is not possible to cancel except for on the phone, alongside the exact same message displayed on the account page

I respond, reaffirming that this is difficult for me due to a disibility, that this is me giving them notice to cancel, and any payments taken will be reported to my card issuer as unauthorized, asking for this to be escalated

I then receive a very blunt email asking for my account number. I match their tone, replying with 'as per my first email, my account number is XYZ', and within ten minutes I see on my account page that my subscription is no longer active, hooray

Is employing aggressive anti-cancellation tactics like this legal, and if not who do I report it to? The whole experience has left a sour taste in my mouth and there is absolutely no reason not to provide a simple 'cancel trial' button other than to make cancellation more difficult

I'm in England but I guess the laws governing stuff like this will be UK-wide, but NAL so unsure
