I'm up a creek with Amex

Fair Billing Act or some similar anti-consumer nonsense restricts billing disputes to 60 days - since I paid a year in advance, I'm out the $200+ for remainder of my two year package.
Since I need to keep a basic landline, which costs $28 w/tax, and replacement VOIP through Vonage would run $19 a month with taxes and fees, it looks like the best deal is to add a few extra services to my landline and call it a day.
