It would be helpful if you could check it out now so that others who might find themselves in the same position know that there's a solution.
There are three ways of trying out Ancestry, the first two apply if you register for a trial period of 14 days. and third if you just take up a subscription without a trial. (Note monthly subscriptions are different - see end).
(a) You register for a 14 day free Trial (you will need to register your Debit/Credit cards) and be made aware of the subscription offer at the end of the Trial.
(b) You take advantage of the Trial and do not cancel within the Trial period so a subscription charge is billed the day after the Trial ends.
(c) You take up the offer of a subscription without a trial period and the billing period commences the day the subscription is taken out.
If you wish to cancel:
(a) You may cancel
within the Trial period without charge.
(b) You do not cancel within the Trial period and are billed for the Subscription. You now have 30 days from the date the subscription commenced (not the trial) to cancel for a FULL REFUND paid back via your Debit/Credit card.
(c) You have 30 days to effect cancellation from subscription commencement for a FULL REFUND. (Note this applies to Gift subscriptions also).
If outside the cancellation period:
(b) & (c) If cancellation is not affected within 30 days then NO REFUND is due but "
you will retain access to the relevant services for the remainder of your subscription period, after which your subscription will be cancelled"
Monthly subscriptions: These may be cancelled at any time prior to two business days before your renewal date, but NO REFUND is given. Any time remaining will allow access to services but if no cancellation is effected prior to two business days, you will be billed for another month and the same cancellation condition will apply.
In my own case (my wife's subscription renewal) is now in excess of 30 days so no refund will be given. I could cancel and continue using until subscription expiry or do so at a later date before expiry.
I hope the above will be of help. Ancestry's Renewal and Cancellation terms can be checked by searching for same at Ancestry.
