I would advise emailing the company with the exact date and time if you have it of the number of attempts you made trying to cancel the subscription. You should receive an automated email with a reference number on it. It may take them a few days to get back to you. In the meantime, contact your bank. The bank will be able to tell you if My Heritage has actually claimed the funds out of your account as this can take several days to leave your account even if it is showing up on your online statement as a debit. Either way, you cannot stop the funds being taken out of your account; cancelling your card will also not prevent this. What you must do is normally wait between 3 - 5 days of the money acruelly leaving your account for the banks to then raise a disputed action to reclaim the funds. Having your email outline your attempts to cancel the trial within the correct time frame will assist the bank with documentary evidence. Hope this helps.
