What's even worse is they do what amounts to a bait-and-switch. I call up Comcast to get Internet service. Then they quote me a price on the phone and I sign up. However, the price they quote is only the "base" price. There's tons of fees and taxes that aren't disclosed until you get your bill. There's literary no limits to these line items and they can increase at any time. None of these were ever disclosed to me over the phone. I can't understand how this is legal. They also did hard pull on my credit without my explicit permission.
