I've decided to take the plunge into high-speed internet, and am switching companies to do it. Company B is handling my cable TV, and I saw a bundle / promotion on their website (confirmed by the CSR) that included high-speed internet for not that much more a month than I'm paying now.
How much notice do I need to give Company A that I'm cancelling their service? I plan to switch on Tuesday afternoon sometime. Would Tuesday morning work?
