I cancelled the sub a few weeks ago - and it seems to now be very longwinded to do so. I kept going till eventually I got an email to acknowledge I had cancelled and that the current sub would expire on the end date. At that stage my account said it was Expiring on 30th Nov and then this morning it said Registered Guest.
It is worth being sure you have cancelled before the expiry date, I would definitely not have renewed at the renewal price of £179.99, especially as we are about to get the 1921 census elsewhere and it will be years before Ancestry have it.
