Pricing

After wasting 4 hours today with 3 agents I lost all of my access to the xfinity channels Thanks! I had requested to keep. Now it won’t let me back to adding the programs even though I have confirmation that the channels I required were included in the new price I was quoted today. With a military and device discount.
How do I get back access to the channels I was promised? I have screen shots and download of the entire 4 hours chat. Please help this long term customer.
