DVR storage

I increased my Cloud DVR capacity to 150 hours yesterday. My cloud storage is still 20 hours. The change is reflected in the upcoming charges, including the partial service month that started yesterday. I have attempted several times to correct the problem using the “Xfinity Assistant” (quotation marks indicate irony), but because this problem does not conform to the extremely limited set of problems the “Assistant” can respond to, I keep getting sent back to the beginning of the “Assistant” help-doom-loop, without ever being able to reach an actual person. I realize that Comcast wants all contact from its paying customers to be screened by automated systems because that is cheaper than live help. However, they really need to work on improving their automated systems, which today are terrible.
