Can't pay bill without driving 65miles to the closest Xfinity Store.....

This is the 2nd month in a row having issues paying my Xfinity Bill.

Last month it said my access to bill pay was denied and I had to have the Xfinity Chat person pay the bill on their end.

This month it says I have to go to the nearest Comcast store to pay my bill. The nearest Comcast store is 65 mi away I cannot drive 65 mi to pay my internet bill when I should be able to pay it online or in the app or over the phone. 

The only difference between the last 2 months and now is I use a new card last month and this month I'm trying to go back to using the original card that I normally use but I can't access any of the bill payment options. 

Also for some reason I have it set where my bill is due on the 15th of every month and every single month it tells me my bill is late being paid even though it's the first of the month and it's not due until the 15th. So no matter what it tells me that my bill is past due even though it actually isn't and I need that fixed as well and I don't know how to fix it and every time I talk to somebody on the phone or in the chat they tell me that they can't fix it. 

I got told I was going to get a call back regarding my bill paying issue however I did not receive a call. And then I talked to somebody again through the chat who told me that they couldn't fix it but that they would escalate it to somebody and I should be able to pay my bill in 2 hours so I waited the 2 hours and I still can't pay my bill so I talked to a third person who told me that they can't fix it and to try again tomorrow.
