ReelVero Keeps Charging Me After I Cancel My Subscription

I had a weekly subscription with Reelvero, which I canceled on 20 October. Despite this cancellation, I am still being charged for the service. The payments are being taken via my Truist bank card through Apple. I have not yet contacted Reelvero, Apple, or Truist customer service about this issue, because I want to clearly state first that I do not accept these ongoing charges after the cancellation date. I request that my Reelvero subscription be immediately and permanently canceled and that all charges taken from my card after 20 October be fully refunded to me. I kindly ask for this matter to be reviewed and resolved as soon as possible.
