Hello Brijmohay,
Welcome to the community!
Sorry to hear of your situation. You should note, though, this forum is community-driven and not intended as a venue for customer services. We would not have access to customer accounts. If you wish to cancel services, you would need to re-contact customer service. I understand your tablet plan might not allow for calls. 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
