Xumo Box Has Major Flaws, wrong channels, wrong account etc.

I am posting this so everyone is aware. Comcast xumo boxes have major glitches. If it is a reuse box be prepared for a long adventure. The first box I received recognized my account but after setup it showed channels for a completely different region and showed recordings and movie purchases from another persons account. There is no way to sign out of the stream app. I exchange the box for another one, this one won’t show any channels at all and won’t work. This one also shows movies that I did not purchase. Now I am on box 3, this one only shows the free internet channels and shows movies that I did not purchase. I opened several tickets and had tier 2 support. No one at xfinity knows what they are doing. The xfinity retail store employees and manager said all the boxes are reused ones and the warehouse might not be properly resetting them. Xfinity definitely isn’t doing things correctly. The xumo box you get from xfinity is not the same xumo box you can purchase directly from xumo, they have their own firmware and software on it with a completely different remote. I have read similar issues on the internet. Senior management at xfinity needs to fix this issue. This has been a huge waste of my time.
