Terrible costumer service

Elijah and his team have been nothing but a headache I have been talking to them for 3 days now and each team member has told me something different. The problem started since I activated my service at xfinity mobile they attached the wrong phone device to the wrong phone number I brought it up to them but they said as long as it doesn’t interfere with my service there was nothing to worry about, now that I wanted to trade in a phone to get a new one I told them I want to trade in my iPhone 16 for a 17 pro, they asked which line that was I gave them the line number and told them that it’s the wrong phone device on the app they said don’t worry we’re aware and what matters is the we pick the correct phone number. When I printed the shipping label to send in my old phone I noticed it said Samsung s24 instead of iPhone 16 I called costumer service to correct it and they told me they would correct the shipping label but I had to wait to activate the phones until they did the correct paperwork, and told me they would be calling me at 9am on Sunday. Sunday came and no call so I decided to call. Another team member (Rosie) answered and said she would change the shipping label but I would have to return the new iPhone wich I had already waited for to ship for 3 days and paid $121 for the service at the store. I asked to speak to a manager and Elijah took the case I explained the situation said give me 20 minutes to fix the issue but didn’t do anything at all and told me I would have to activate the phone then erase everything again and send it back to start a new process and order a new one and wait another 3 days for the exact same phone I would be returning. This team should not be working costumer service, the level of incompetence and lack of communication this team has is unbelievable! I will be taking my business to another company that actually cares about their costumers and has a strong team that provides a reliable service.
