Removing xfi pods & the network

Yesterday i bought a 3 pack of pods.  Today I used the app to remove those 3 pods.  I don't want them.  Bascially its made me the administrator of our network, which i want no parts of.  I am returning them in hopes my nextwork will revert to the way it was before the pods and allow my son to be our administrator.

1-Since i don't want them, what's next, return them to the Xfinity Store?

2-Once removed and returned, will my son be able to take control of the network again?
