End of contract and not being able to see new offers while out of the country

My contract expires in October, and I am currently overseas. I recently received an email from Xfinity about a new five-year offer with no contract. However, I am unable to access any information about my account or the new offer when I log in, either on my laptop or mobile device.

I would like to review the offer and my current account before deciding whether to continue with Xfinity. If I cannot access my account information or receive assistance, I will have to consider other internet service providers when I return to the U.S.

Any advise?
