Free Trial Subscription

Hi. How can I subscribe to a free trial? When I accepted the free trial and inputted my account details, they said that they would send an order summary but I haven’t received any. I waited for months being complacent that they’ll notify me once the free trial ended. When I checked my bank account earlier, a certain amount was deducted and it was AVAST. Now, I have submitted a report but haven’t received any confirmation that they have received my concern/report. What should I do now? Need help asap :frowning: :cry:
