Please help w/internet cancel

Hi, my monthly service fee almost doubled, and I've already installed and committed to another Internet service provider.  I'm working at a new job and trying to get stuff crossed off my list before Christmas. I don't want a scheduled callback three days from now, I'm definitely didn't want to schedule at 6 AM on Sunday, five days from now. Please contact me and assist me with cancellation of my Internet service ASAP. Thank you in advance.
