I have attempted to cancel an unwanted and unauthorised subscription extention on the Build the Delorean series numerous times. I got no answer on the phone and no response to emails so I cancelled the credit card they were taking payment from and got a new one. A month later they took payment from my NEW credit card! How? So I cancelled that one and got another new card AND IT HAPPENED AGAIN! My bank keeps reversing the payments and can't understand how they are accessing my account. Don't sign up for anything with this crappy company - you'll regret it.
