Payment to Twitch does not know why?

I just got an email from Twitch that I sent 4.99 to Teitch Interactive. Why is that happened? Can it be because I have subscribed to 30 people ago and now this extended? If so, how can I disable the auto-renew function for dad.

Thank you

Seems to be a subscription.

You have subscribed to a twitch channel

Yes twitch subscriptions extend automatically if you do not cancel
