I joined actually thinking I was joining Our Time - the payment pages are identical - the two sites seem to be connected in some way... I thought affinity was operating Our Time - but when I went to check my Our Time account I saw I had to pay another subscription...
On signing up it said I had 24 hours to cancel - but there was a notice on my account saying that I couldn't cancel the repeat payment until all 3 payments had been made.
Having read the reviews about difficulties in cancelling I immediately contacted my credit card - unfortunatley they had to honour the first payment but will block all future payments - you are legally within your rights to do this - check with citizen advice web page...
