It's a free download as it states but you need to give your card details as after 7 days, if you do no cancel they will automatically debit your account. Yes it states on terms and conditions and on the email that they send to confirm but do not get caught out like me with the small print and please read wisely to what you are signing up for! I should have known better and paid closer attention... make sure you do! And don't bother calling to dispute as they are legally covered.
You had selected the 7 day free trial subscription offer on October 20th and you cancelled the account on November 21/15. On October 27/15, you were charge for the upcoming month as per the terms of the offer you selected. The offer does state the need to cancel within 7 days
Or the account will convert to the monthly plan until cancelled. The credit card page repeats the same information. The next page is the receipt which also has the cancellation information including the date and time to cancel by. We emailed you moments after you selected the 7 day free trial offer and that email contains the cancellation information including the date and time to cancel by which is in bold font. We also emailed you on October 28/15. Since you did not cancel until November 21/15, you were charged for one month. Your account is now cancelled and there is no further billing.
