An oldie but a goodie, In Sewer Ant ****ers.

Renual from Bikesure 240 quid.
Small print : "We'll take it off your credit card, ring us if you don't like it, only 33p a minute while you are on hold

"
So:
Email their general enquiry people to stop renual

Go compare to find they quote £190.

Accept and fill in form telling them to go talk to themselves

You just know they are going to query their own internal communication

If only we had REGO instead of this state sponsored mugging.
