Xfinity Support Deliberately Providing False Information

We've been Xfinity INternet & Mobile customers for 7+ years. On Sept.14 I ordered two new iPhones as part of upgrading our existing devices (and paid the upfront fees in full). I was notified that they would be delivered on Sept.19. On Sept.19 I was told that the delivery by Fedex could not be made, because I wasn't home (we were). That was untrue, what really happened was that Xfinity had not given Fedex my full delivery address (they left out apartment number), so they couldn't deliver. Between Sept.19 and today I spoke with several(8 and counting) different support agents, the most recent telling me that I will have my phone by 4pm EST today (Sept.23), that was almost three hours ago. Each of these agents flat out lied to my face with smarmy "oh we'll sort this out, don't you worry" messages, none of them made any effort to update the delivery address and get the correct address to Fedex. I then phoned Fedex earlier today, and they told me that Xfinity has made no contact, and nobody from their team has updated the delivery address. So I was intentionally provided false information by these so-called support agents.

Has anyone else had this happen to them recently, and more importantly, did these agents also ask you to fill out your social security number using a link in the chat? I'm starting to get the feeling that there's something untoward going on at Comcast. I saved all the chat transcripts, and the names of the agents, what should I do? You can't even get someone on the phone who knows what's going on.
