Executive Customer Relations - Customer Retention

I have been going through this for a few years now.  I work 3 jobs and do not always have time to spend a minimum of 60 minutes, more often than not 95 minutes dealing with comcast support.  I am being charged for 5 boxes on my account.  I have 2 active boxes on my account.  Everytime I call to have 3 removed they confirm 3 are not active but cannot onfirm they received them back.  That being aid they are charging me 14 dollars a month times 3 in perpetuity.  I cannot tell you how many hours I have logged trying to resolve this with support.  Each time they credit my account for one month and then the next month go right back to charging me for 3 additional boxes
