correct billing

This is the most obnoxious company I have ever dealt with. They were supposed to change my billing before the billing cycle of the 5th to save money. I downsized because I live on a fixed income. I was assured it would be taken care of but was not and won't not go into effect until 7/15. I want my credit due me. Your Xfinity assistant is a joke, it has been running me in circles for 3 days now. Getting to a human is impossible. I want  what you promised me. I have no there choices since you seem to have a monopoly on service in this area. I have a bundle with internet, unlimited phone and 10 cable channels at 116.04 a month and you expect me to may an additional $126.24 for this month. Absolutely not! Also I asked you to take [Edited: "Personal Information - Email Address"] off my accpunt 6 times and nothing was done.
