There might be different reasons as to why you might have been charged during your trial.
Charged Immediately After Subscribing
Authorization Hold
If you see a USD 1.00 charge on your bank statement, this is just an authorization hold to confirm the billing information that's been submitted for your Viki Pass subscription. This hold is instantly reversed and never collected by Viki. However, some banks take a little longer than others to reverse this fully, so it may remain a pending transaction for up to 5 days before being removed from your account.

There is only one trial per Google ID. This means that if you subscribed using a Google ID that had signed up for a trial or subscribed before, you would be charged immediately without a free trial.
