Hello signed up for the 7 day trial, but even though I've followed the instructions to cancel via the Google App, It's still showing a full years membership cost renewing next year and it has charged me to my Google account. The customer support service says they do not recognize my account when I have sent them screenshots of the receipt. I really do not understand what is going on. Their refund policy, says that if you are satisfied with the service, you can get a refund in the first 14 days, please help me with the situation.
