Unauthorized automatic MTN subscription to Reycreo service

MTN Automatically subscribed me to "Reycreo" WITHOUT MY PERMISSION. I Received SMS on 19/01/2020 thanking me for "my subscription"to the Reycreo service. I DID NOT subscribe to this game service. Why was I automatically subscribed to this without my permission to get charged a monthly fee of R9.00. Have already unsubscribed. This is THEFT! Stop playing dirty games MTN!!!
