Still have not had my outside cable buried in yard PRIVATE MESSAGE ME!

I am a new customer to ATT with home Uverse TV and internet service. I was told that on September 14th, my outside cable line would be buried in my yard.  2 men arrived, walked the cable line, got back into their vehicle and left without burying the line. I called the buried cable department, and was told they would contact the contractor and have them call me.  No one called.  I called the buried cable department again, and was told the same thing. I requested to speak to a supervisor.  She stated she would make this a personal issue for herself, as it was over 2 weeks past the original date the line was to be buried, and she would call me back with the status of having my cable line buried.  Never heard from her again!  It is now the 10th of October, 4 days shy of 1 month since ATT told me my cable line would be buried, and yet it still sits in my yard.....unburied.  I made a commitment when I moved into this new home by leaving Xfinity and going with ATT for my cable and internet provider.  I agreed to a 2 year contract, and as part of that agreement, I am expected to meet my obligation to ATT...pay my bill on time etc.  ATT has an obligation on their end to provide cable tv and internet service to me....and they also have an obligation to bury the cable in my yard as promised.....in a reasonable amount of time.  It is nearly 1 month late now....no one has returned calls to me as promised, and no contractor has buried the cable as ATT stated they would.  This is the last ditch effort on my part in demanding that ATT honor their commitment and send someone to bury the cable.  If I don't hear back from someone at ATT in a timely fashion....and they honor their obligation and bury the cable as stated when I signed my contract with them....I will return all equipment to ATT and go back to Xfinity or go with Spectrum....and I WILL NOT pay an early termination fee for breaking the contract....ATT has not lived up to their promise to have the cable buried in a timely fashion....therefore the contract with them is not valid.  I NEVER had this kind of issue with Xfinity....EVER.  The only reason I changed was to save a little money....and I think I have made a terrible error by dropping Xfinity and going with ATT.  However, one last chance....maybe someone with this company cares about customer service and will fix this problem....we shall see.
