Just avoid Cycling World. I took out a trial subscription, cancelled it as soon as the first issue arrived (because it was rubbish) and cancelled my direct debit. They then debited my account anyway.
My bank refunded me, but seemingly never got the money back from CW as the crappy magazine still turns up now. I've sent each one back marked 'Return to sender - remove from database' and still they come.
Called them and written to them, each time they've promised to remove me from their database and still the magazines arrive.
I've now made a formal complaint to the Information Commissioner - hopefully that will do the trick. If they debit my account again at the end of the year, I'll be reporting them to the Police for fraud.
