MyIQ Didn't Tell Me About Subscription

I recently discovered that MyIQ charged my account 47 pence today, even though I was never clearly informed that I was subscribing to any paid service or plan. I do not see any subscription details or active plan connected to MyIQ anywhere in my account, so I do not understand why this payment was taken. I request that MyIQ immediately cancels any possible subscription or recurring payments linked to my account and confirms that no further charges will be taken from me in the future. If this payment was taken by mistake or without clear consent, I also expect it to be refunded.
