When they first launched AT&T Fiber in my area, I got a promotional offer that stipulated that my monthly payment would be $50/month for life. After getting my first bill I noticed that the bill indicated that my normal monthy rate was higher but it showed the discount so the price would be $50. Me being a skeptic, I called AT&T to verify that this would never go up and ask them why it just didn't say $50. They assured me if would never ever go up. Of course a year later my bill went up. When I called customer service they said they had no knowledge of this offer and told me to basically pound sand. I wish I had never switched to AT&T fiber.
