Call them back and make them fix it.Tivo has been weird for me lately. I had an old series 3 and tivo hd. Online they both say activate for lifetime.. the series 3 for 299.99 and the tivo hd for 399.99. So I decided to activate the series 3.. a few months later, still being charged 9.99 a month. SO I called them, they fixed it .. and guess what? I get a bill for 399.99 for my series 3 and now the tivo hd is saying online activate for lifetime for 499.99
Whats up with that?
Shame on you tivo
They offered lifetime for $299.99 and you accepted.
Offer and acceptance.
Anyone who ever watched "Paper Chase" or any other lawyer show can tell you.
That's a legally binding contract.
They didn't fulfill their end of it until you pointed out to them that they hadn't fulfilled their end of it. By that time the price of lifetime had changed, which is where they made the mistake, but the change doesn't apply to you, because you had a legally binding contract for lifetime at $299.99.
They owe you a refund of $100 and of all of the monthly charges wrongly imposed since you accepted their offer.
