I am making this post to gain access to direct messages

No, I am trying to do some updates to the users/email addresses on my Xfinity account. The account is in my name. The site requires the entry of additional credentials to login to administrate users on the account. The problem is that on one the challenges is to provide my service address. However, the system will not grant access because it does not recognize my address as a valid one, even when I copy the exact address from my account info and paste it into the address challenge field. In fact the system offers only two valid addresses to put into the field and it accepts neither of them. How can administer my subordinate accounts and update their passwords if thew system does not grant me the needed access to do this? Any assistance is much appreciated!

I did try typing it out several times to no avail. I'll try your other suggestions - thank you!
