Rain billing and service

I registered and activated my profile/account in October, paying the prorated amount. However, in November, I was unexpectedly charged double. At first, I assumed it was for the upcoming month of December. To my dismay, I was once again debited today. When I attempted to contact their customer service, it proved to be a frustrating experience as they kept me on hold and disconnected the call without resolving my concerns. It is quite perplexing that I have only had their router for two and a quarter months, yet I have already made four payments. This situation appears to be a deception or ****.
