I experienced the same. It seems I inadvertently subscribed to 'Complete Savings' when I purchased something online. I had no intention of doing this and had never heard of them before hand. If there was mention of this subscription, it was extremely unclear. They started to take £18 per month from my account. Rather than contacting them, I spoke to my bank who successfully disputed the transactions and I got my money back that way. However, today I received £18 from them! Which worries me, because it suggests they still have my bank details on their records. I'm following this up with my bank and have sent 'Complete Savings' an email asking them to cancel what ever account I have with them and insisting that they remove my details from their systems.
