Hello Jols08,
Welcome to the community!
If you would like to cancel your device protection, you would need to contact customer service. Alternatively, you might consider sending @FidoSolutions a PM. Once they verify some information, they'll also be able to access your account. In addition, they can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers
