The clerk at the store is mis-informed.
I'm a current Spectrum subscriber - carried over from Time Warner.
As am I, but we are grandfathered into spectrum.
Making any change, to the timewarner account, will trigger a switch to new spectrum account.
Spectrum will cancel the (GF) timewarner account and create a new spectrum account.
Don't ask me how I know.
So I think the OP's problem as he states below, could just be the spectrum box is inclusive of the package.
The cost of the box cannot be separated from the package price.
Still, it doesn't hurt to pitch a b-itch at the FCC.
I have the tuning adapter and cable card and they are working great with my TIVOs. I'm sure they would allow me to return the cable box if their system allowed them, but I suspect that the Spectrum system will not allow them to remove the box from their promo plan. Is there anything in clear writing from the FCC that states that cable companies cannot force the lease of equipment on customers?
I don't recall seeing anything from FCC. But I have not kept current with evolving(?) regulations.
Wondering is there a "line item" with a price, greater than $0.00 for the cable box?
