That was all to the good. Then I bought the new modem, got home and called to have it registered. The twit ruined what should have been the easiest part. The stumbling block seemed to be that I couldn't recite either my Comcast account number, or what the amount of the last bill amount was. That bill is paid automatically by the bank. I open the bill long enough to verify all is well with the account, tear it up and toss it.
