I wouldn't worry about it!
I had a better call from a customer last week. 2 years ago we installed her Dish, and for whatever reason she decided to cancel her service and go back to Cable.
The Cable company came out and saw that we had removed all her cable wiring and configured it to work with her Dish, and now wants to charge her $25 to correct the wiring so she can get Cable installed.
The customer calls my office and argues with me for 20 minutes trying to get me to re-imburse her the $25 that she has to pay because we re-configured her wiring to work with Satellite.
She made me talk to the cable installer when he was there trying to charge her, and he got a good laugh when I said that she honestly expects me to pay $25 to have you re-wire her home so I'll loose her account.
The only problem I can see with this lady is if she is still in the chargeback period
