someone to fix my mobile account

I have spent hours and hours on the phone with customer support on multiple occasions in the past 3 weeks.  I have been sent to my local xfinity store for assistance to be told after driving 30 minutes to get there that I need to go to a corportate Xfinity store.  I have made the 1 hour drive to a corporate Xfinity store to sit there for 4 hours just to leave with nothing resolved or corrected on my account.  They opened 2 tickets for me and I STILL have no answers or corrections to my account.  I am BEYOND frustrated and completey shocked on the service that I am NOT getting from Xfinity after being a customer for over 20 years!  I need help on my mobile account asap and on my overall Xfinity/internet/home account.  Is there anyone that knows what they are doing??  Without the lies and promises and empty resolutions??
