I just renewed my subscritpion, throughout the payment transaction via Cleverbridge I looked to see if it was going to ask if I agreed to an automatic renewal but this was nowhere to be found, however since I have a lot of experience with such things I went straight to my “pre-approved payments” list and sure enough it was there and marked as active, so cancelled it. The receipt from Cleverbridge mentionned the following:
[i]
NOTE: Your license is valid from the day of purchase not the day of activation.
You are subscribed to a multiple payment product.
The next payment of £49.99 is due on 9/2/2017.
[/i]
So this gave me a big fat clue
This may help others more innocent people ;D
