Can’t cancel subscription

There is simply nowhere on the website that says “cancel subscription”. I haven’t used the service in forever and was billed annually for $70 today. It seems incredibly difficult to get in touch with support. I sent them an email with a screenshot of my emailed receipt asking for them to cancel my subscription and refund the $70 because I can’t afford it. The lack of intuitiveness and not simply having a “cancel subscription” button is very concerning. I see an option to “delete account”, but that doesn’t say it’ll cancel the subscription. I’m worried that if I delete my account I’ll still be charged annually. I really need help in getting the refund that I seem to be eligible for as I was charged today and sent them an email the SAME day
