Porch Thief Disabled Video Doorbell

I am reposting this because the original location is not the appropriate place. At 1:37 pm yesterday, I have a motion activated video showing a fedex package being delivered to my porch. At 1:47 pm, 10 minutes later, I have a motion activated video, but it is completly black, with no sound. Twenty minutes later, I have the next motion activated video of me on the porch getting my mail, and there is no box on the porch. It looks like somehow the porch thief was able to hack into the Ring Doorbel and erase the video of them stealing the box. They didnt delete the video, they just blanked it out. They did not cover the camera up, or I would have still been able to hear background noises that are loud in this area, but the video is totally silent, and solid black. Has anybody else had this happen? I called customer service. They looked into it and verified what I described above, then after about 20 minutes on hold, they came back and said that what they were seeing was impossible so they blew me off. My WiFi has a complex password and wpa2 authentication with a full firewall, so there is not much more I can do from this end. I have been looking more on the internet and talking to the police. It looks like what likely happened is that the porch thieves had a transmitter that scrambled the WiFi signal. The Ring devices operate over your WiFi network, and they only work when your WiFi is working. Since the doorbell uploads the video in real time to the internet, if your wifi is compromised during the robbery, the Ring devices cannot communicate with you and they can't properly upload the video. You are basically left with nada during the thieves visit. No motion notification, and no video. When they approach your house, the wifi gets scrambled and Ring goes down, when they leave, your WiFi and Ring devices go back to normal. The whole process probably lasts 2 minutes or less. The transmitter can be anything from a modified baby monitor, to a walkie talkie that has been adjusted to broadcast on the 2.4 and 5 Ghz frequencies. This WiFi scrambling technique will effect all security devices that operate on your WiFi network, not just Ring. At this point, I can't trust Ring for anything dealing with security.
