Help me find a way to get a replacement phone lost in transit

I ordered a replacement iPhone on 11/17 as mine is not functioning through apple care, it was supposed to be delivered 11/18 but never appeared. I contacted fedex and was told to reach out to apple. I called 11/22 and spoke to several agents for well over an hour. They said they would resolve it and get back to me in 2 business days, 2 business days pass and I receive an almost unintelligible email saying wait 2 more business days. I call again that day 11/23, after a very long call, the advisor promised to call me at 10:45am in 2 business days so we can reorder the phone I ordered on 11/17. The advisor calls at 7:45am instead of at the scheduled time. The call was to a family members phone and they missed it since we were scheduled to meet at 10:30am for the call so I could take it. I call in again to apple support today, they do not apologize, refuse to get me in touch with that agent and offer zero means of ordering the phone that fedex/apple lost in transit on 11/18. I feel so unsafe home alone with no working phone. I’ve lost hours of work time and asked people to watch my kids trying to resolve this and I’m getting desperate, someone please help. I just want the phone that was supposed to be delivered. I tried submitting a new request myself online but can’t because none of the agents closed my initial request. Same issue going in store. Help!!! It’s not my fault my phone was lost and I’ve tried everything.
