HBO Channels NOT included with DirectTV stream with ATT Unlimited plan??

Hello,

We recently switched over from ATT Uverse to DirectTv Streaming.  We have an ATT Unlimited Plan and had access to not only the HO Max app but also the HBO channels themselves.

When switching over from Uverse, we were initially told that we'd only have access to the HBO Max app thru DirectTV stream as part of ATT Unlimited.  In other words, we'd have access only to the App, not the channels themselves.  I then called back to confirm some other info, and we were told by a different representative that the previous info was incorrect, that we WOULD see the channels themselves, free of charge, in combination with ATT Unlimited.  I confirmed that about 20 times so that there was NO confusion.  We switched over and that's all been fine until roughly a week ago.  Last week, the channels just disappeared from our Streaming guide.  We still have access to the App.  I didn't change anything.  Chatted and called (two different agents) and they're saying that ATT Unlimited only grants access to the App, not the channels in the Guide.  And the reason that I lost access to the channels in the guide is because a "trial period ended" even though I never signed up for nor cancelled this trial period.

Beyond frustrated at ATT for the confusion (at best) or deception (at worst).  Anyone else have a similar situation with accessing HBO channels as part of an Unlimited cell package?  Would love to know how this was resolved.
