Rain refusing to cancel old subscription.

Since the end of August - Mid September, I have been requesting a call back to cancel a rain subscription, which it seems is being ignored. I was "upgraded" to a newer model router but the old one was never removed from my account. Despite my efforts to have the old subscription removed from my account, Rain has been collecting payment for both routers. I even tried canceling through the app but conveniently my collection address does not appear In their search bar.
