cell phone issue

I am currently an xfinity customer for Wi-Fi service for a slip at a marina location.  I most recently called xfinity on 9/20/2024 to switch from AT&T to xfinity which also involved a new cell phone from xfinity with this switch. 

During the closing of the conversation, xfinityu 'Lakisha" informed me the new cell phone and sim card would be delivered to the marina where i have service (i was told that my home address is not serviced by xfinity).  
 explained that i do not live at the marina, i would not be available to receive the package.  Lakisha stated that once i received tracking information from the USPS i could change the delivery location.  

The tracking number came from FEDEX.  When i tried to change the delivery, FEDEX said can only be changed by SENDER.   I called xfinity on 9/22/2023 and was informed 'they' cannot change the delivery.  I asked xfinity to cancel, i was informed that xfinity cannot cancel.  I physically went to a FedEX office and was informed delivery can only be changed by the sender.

I do not want the the product or service from xfinity.  I was lied to by xfinity during my call with Lakisha.
