Fort Lauderdale, FL
Returned to Sender
I took the two free adapters as soon as they announced them several years ago. All I did was activate them and made sure they worked. I never watched TV on them again.
When I saw the upcharge on my last bill, I took them back and got full credit of $3.98 (2@ $1.99 each).
If I have company coming in from out of town I'll just go down to the local service center and pick up a converter and take it back when my guests leave.
