Need assistance with Cujo security – CUJO Review

I purchased this device from QVC with free subscription. Upon buying my own router(TP LINK), I needed help with setting it up. I had to use my computer and enter the info provided. After setting it up, the vendor was still signed into my account and showing under devices. I called and was able ( I thought to get it corrected). I changed back to Comcast and am now using their XFI only to have someone named MURATA show up on my account as VENDOR. I sent a previous email and it went away. Hours later it was showing on my account again. And I never received any alerts after hooking it up again. So I’ve unplugged it and even tried deleting the app, only to find out it doesn’t let me download it again. I paid a lot of money for this device. There should be a method to contact you other than email. If you’re still selling it on Amazon, surely you still have customer support. Please respond with a phone number
