Who changed Multi-device 1year CAMPlus Service to 1 device-multi-year service

I have a total of 5 V3 cameras, and I have purchased cam-plus services for 3 devices. A few days ago, I found 2 of them stopped working. Then I found my original 3 device 1year service somehow was turned to 1 device 3 year services. Who did that?

You might want to reach out to support on that one.
