Customer service is lying to me! Why does Xfinity not honor their offers from the website?

Hello,

I bought a new iPhone that you were offering at $400 discount on 4/25/25. This is still the current offer.

It was delivered on 4/30/25 and I activated it on 5/10/25 and ported a number from a different carrier to meet all conditions for the phone's promoted discount. However on my first bill with the new phone on it there is no discount given.

I tried to resolve it through a live chat and was promised at the end, that my account was updated and the issue was fully resolved.

Well, NOTHING was done!

I was overcharged and the preview of the upcoming bill shows also no credits.

Why am I being lied to by your customer service representative?

Why is it so hard to just do what you are promoting?

I have screenshots and chat transcripts that prove my points. Where can I upload them?

Looking forward for some answers.

Andy
