Disappointed in your Customer Service for Internet

I am VERY disappointed in your overall service.  I was "convinced" by your cell phone sales person to try the bundled Direct T.V. + Phone + Internet.  I had nothing but trouble from the scheduled installation.  Aug 15 no one showed up.  August 27, the disaster started.  We turned down the Direct T.V. before it was installed because the technician didn't install it correctly.  Had issues with the landline (2 eight hour days wasted - Technicians came out twice) and service was never correct.  Since it is VOiP, I knew the internet was needed for service.   So although the speed was not acceptable, I was concentrating on the landline.  6 weeks on 10/5 I called to cancel and was told I could not cancel until the number was ported over to the other provider.  The phone number was FINALLY ported over on 10/24/18.  I called to cancel the AT& T service 10/25/18.   I then received a statement and was assessed with an EARLY TERMINATION FEE!!!!! of $157.02  I called both your customer service department and loyalty group and was essentially told, "...too bad you didn't call us within 30 days so you have to pay the fee..."  This is unacceptable service.  I will continue to post on any forum I can about the bad service I have received from AT&T unless this fee is rescinded.  I feel as though I've been punished twice.  First by poor service and now penalized with an early termination fee.   My cell phone will be coming up for renewal.   If this is not resolved to my satisfaction, you know what I will be forced to do.  Sad to come to this after having two generations of AT& T employees in my family.
