$10 Credit for Direct payments from my bank account

I just recently had to make some changes to my account.  I was paying $71 a month for basic internet service and requested to lower my bill.  At first I was told that my bill could be lower by $10 - and the first consultant added that to my account.  She then siad that I would have to talk to the Loyalty Department.  I was transferred and started to explain that I have the lower internet however paying $71 a month.  The Loyalty Rep went on to explain that I was only pay $61 because of the $10 credit for Auto Pay - I explained that was just put onto my bill - she then put my on hold.  She came back and tried to explain that I did not have the correct package - I explained that it should not mater what package and the Auto Pay has nothing to do with package.  She then said what do you want me to do?

She was able to lower my bill to $50 a month plus the $10 Auto Pay credit - she then said she was going to give a $30 credit and that is all she can do.  Which makes me think that I should be getting more of a credit.   

I was able to review my online bill - seems that I have had Auto Pay for a long time.  

I would like someone to review my bills to see what other credit I should be getting for Xfinity's error.

Thanks you,
