2 product discount and auto pay discount

Prior to April 18 2021 I had a preferred package including digital preferred,blast internet and XFINITY voice unlimited @$129.95.  I was also charged an internet speed increase called Extreme 105 internet $10.  My TV Digital starter is through my community.  I have had this service since 2018.  Prior to 2018 I was at a different address with a similar package in the same town.  I have no idea when I enrolled in autopay and paperless billing but it was at least in 2018.   After speaking with several others in my area who are paying much less than I do, I went to my local xfinity store and was told that I was was overpaying but they could not make a change since I am part of "bulk" service.  So on 4/18/21 I called.  I was told I DID NOT have Blast! even though my package said I did  that I was only getting extreme.   If I changed to Blast! and kept all other services I would save approx $30 per month.  If I had never called I would not have known I was not getting the services my bill said I had.  So of course I made the change.    Now that I have my new bill, I see that the only reason it is less than before is because of  discounts of $20 for 2 products and $10 for autopay and paperless billing.  The cost on my digital preferred, voice and Blast is actually more than what I was paying before.   

MY QUESTION IS:  why was I not getting those discounts before?   I did a chat was was told they are new discounts, then was told they are old discounts but they did not apply to my "old market "plan and that now I have a "new market" plan.  Than is ridiculous.   How does Xfinity explain this?  Old Market is from 2018?  I believe I am entitled to a adjustment of prior fees to include at minimum the auto pay and paperless billing discount of $10 for as long as that discount was in effect.
