“Disqualified” from promotion with account in perfect state

So frustrating! I opened an account and activated internet services on May 12th 2026 with a promotion that included a $100 Amazon gift card after 90 days of my account in good standing. Well, it’s been over 90 days and I have automated payment set up that have come out on time every pay cycle and have not made any changes or adjustments to my account since I got it on May 12th. But when I went to check the status of my gift card through their incentive tracker, it’s simply said “DISQUALIFIED- TIER OF SERVICE CHANGE” which is just not true! I contacted customer service who was absolutely no help!! So so frustrating!!
