Wait. Wait until next week. Do nothing for one week (except cutting off all and any money related things, like the cell account).
If you still want to do all of this in one week, and you are doing it for YOU, then act on it and do it.
Been down vindictive road... (My Motto used to be don't get mad, just get EVEN!). It feels good for awhile but eventually it doesn't any more.
Better to give it up to your HP for now. The issue is going no where, so it can keep for a week. Stick it on a shelf for now.
