Canal plus takes 20 a month from me without ever having subscribed to their service.
it's been 4 months or 80 !
I sent them a mail in AR, they replied that I had been registered by a bouygues telecom advisor, outside I never asked to subscribe to canal plus!

These are thieves' practices! I will have to file a complaint if I am not reimbursed and the withdrawals do not stop!
