And a conclusion (I hope) to the previous comcastic, indeed! post:
I decided to pay the $18.38 owed to Comcast and be done with it. The collections group offered to take payment online (instead of via a check mailed to them), but when I got to the part of their online payment form that asked for credit card info, I saw I'd be billed an additional $5 service fee for using my credit card.
I instead closed the browser window and paid $0.37 for a stamp to send in the check and use up at least $5 of their resources opening my mail, endorsing the check, crediting my account and depositing my check.
It continues to amaze me how bass-ackwards the fee system for conducting business online is at some places. Shouldn't the cost savings for the automated process be passed on to those of us who are not taking up the time of some accounts receivable clerk to process paper-based payments?
Perhaps in another life time.
In any case, good bye, Comcast. And good riddance.
