Double Billing every month

I have called 4 different times in the past year for being double billed for my Ring service. Each time the Rep assures me that it won’t happen again, well here we are again this month billed again. I have 6 cameras and they bill me for another camera separately every month, all same name, address, phone number, and IP address. I reccommend not using this service since they can’t, won’t or don’t know how to correct this. Tomorrow I will be calling and cancellng RING and blockng my credit card number they have. Folks find an alternative service
