Trying to change plans – Xfinity My Account Review

I have been trying for three days to change my plan. I get to the point to check out and it won’t let me. It just keeps kicking me back to plan review. I didn’t want to believe the horror stories about this company and the bad service you get when trying to cancel service or downsize plan. But this company is horrible for customer service.
