First, I would log into your Cox account and check your Data Usage charts to ensure it's true. I've read posts of erroneous spikes and then later, the subscriber will report the spikes had disappeared from the charts. Sometimes the measurements are off, the system will send a text and then correct itself. Keep an eye on any corrections for the next couple days.
Second, if Panoramic cannot provide the requester of the spikes (device), Cox should research the provider of the spikes (website). This information should be in the metadata of their logs.
I feel Complete Care failed you because this service should have notified you to upgrade your Panoramic to the latest and greatest. You're not only paying good money to rent, but also good money for Cox to care for you.
This all reads too convenient for Cox. Cox reports spikes but since you rent their older Panoramic, there is nothing you can do about it.
