I canceled a R15 on my account. Since it is a leased box, they want me to send it back. I paid the lease fee. I have 4 other receivers on my account. Can I call and inform them that I want to keep it just in case I ever want to reactivate it as long as my account is in good standing and I don't cancel service? This way I can avoid another lease fee in the future should I ever want another DVR on the account.
