Worst customer service I have ever had

Worst customer service I have ever had.   This seems to be a recurring theme.   I am a 30 year customer,  but I am ready to end that relationship due toXfinity not honoring anything I have been told this year,  and wasting hours of my time.  Wayne,  a supervisor I spoke to last time,  told me he would call me today at 1:00, to confirm my bill and make sure the corrections went through.   He never called.   It's now 3:30.  I checked my account and the wrong information is still showing for what you say I owe.   I have confirmation emails from you,  that don't match the information on what you say I owe.   I have wasted over 10 hours on the phone,  trying to resolve this.   You make it almost impossible to contact a person.   I will pay the $233.66 that was the original amount given to me, and confirmed by an email on Jan 5.  I am done wasting my time with a company that doesn't honor what they say, and clearly has no regard for their customers,  or their time.
