Cannot change plan or view offers online
I am not able to change my plan or view offers online. Whenever I go to the "change plan" tab after signing into my account, I always get this error message :
Looks like you'll need some extra help completing your order.
Thanks for getting started! Since Flex is in your plan, the Xfinity Assistant can help complete your order online. Or, you can call 1-800-XFINITY.
I tried calling Xfinity and using the assistant but they are unable to understand the problem or help. I checked the messages posted here and found that this has been a common problem across lots of customers over the course of 2020 and seems to be related to the "Flex" service that was enabled for free on my account. Although there were comments in early 2020 saying that this issue is being looked into, it doesn't seem like it has been resolved yet! Some posts suggest that canceling the Flex service resolved their issue and they were able to view their internet offers and select new plans, but I can't seem to find a way to cancel Flex online either. Can someone help?
p.s. I have internet only service but added Flex which was offered for free last year.
