Billing / Promos HOW DOES AT&T / DIRECTV LIVE WITH THEMSELVES???

SECOND TIME POSTING THIS - and this time there's more.  Approx 3 months ago got a call from agent that I was being offered free HBO for one year for being a loyal customer, no strings attached.  That lasted approx. 5 weeks before I no longer had access to HBO (and I got hooked on GOT).  I called to inquire and they would not acknowledge what happened, would not honor the offer, but tried to sell me HBO.  So, obviously a scam - lie, deceive, get people hooked, then try to squeeze money out of them.  I came on here to complain and someone actually got back to me to let me know that my one year of free HBO would be honored.  In fact, he went on about it, as if they were doing me a favor (by doing what they said they'd do) and he was 100% adamant that I would have free HBO for one year.  So I did get my free access back...for about a month.  I've still got access to HBO, but my bill has gone up $31/month!  So now it appears I'm being charged for HBO (after only less than 3 months free) AND my base rate went up as well.  AWESOME.  I had previously agreed to a 2 year contract beginning 11/2018 and that is gone - after only 5 months!!  TWO promises have been broken - the 2-year contract bas rate and free HBO for one year.  I just spent over an hour chatting with someone about it to zero avail.  I spoke with a supervisor who didn't seem to have any idea where my info came from and said the free HBO is only for wireless customers, which I have never been and never heard of (they gave me free HBO for a bit which proves it).  I'm sure many people just give up because it's so frustrating and time-consuming!  Such horrible business practices!!!!!
