Amazon gift card hoax

I signed up through a concierge service that said Xfinity was offering a $200 Amazon gift card if you signed up for the larger package which was only $10 more a month. They said it would take 4 to 6 weeks to arrive. I found this forum in read that it takes 3 months so I waited. I signed up back in April. I reached out to the concierge service to confirm that the incentive was on my account and they told me it's all handled through Xfinity. I see no record anywhere on any of my Xfinity accounts of the incentive and the tracking website shows the same. I feel like I got scammed. I wouldn't have chosen the bigger package without that incentive. I'm locked into the plan for 2 years. They stand to make an extra $240 that they wouldn't have if I wasn't offered the gift card. So I'm hoping Xfinity does the right thing and follows through with their promise.

It's also interesting when I tag the word scam, everything I just typed is lost and I have to refresh the page.
