Very frustrated

I have been researching smart watches for a few months and finally decided to purchase an Apple Watch Ultra 2. I used the promo code and received $150 off. I placed my order and got an email saying order was placed. I noticed my bank account was charged the up front amount. However after a few hours there was no Fedex Tracking number issued. So I got into the chat within Xfinity App. As I was inquiring about when I'd get a Fedex tracking number I was told it could take 24 hours. Ok so next day after 24 hours still no Fedex tracking number. I got back in the chat, got an agent after having to type agent multiple times. The guy helping me said he would look into it, he asked if I need help while I was waiting so I decided to ask price for an Apple Watch Series 9 for my teenage son. He sent me a link and asked me to verify if the IMEI number from his Gabb watch would allow us to bring his number over. Eureka it would! Then I asked about prices and he gave me an amount, I said I would need to talk it over with my wife and requested a document I could print to show my wife. After being told my Fedex tracking number was not available still he said I'd have it by the end of the day. We disconnected but then I saw an email populate saying your order has went through. He ordered the Series 9 watch for me, I never told him to! I tried getting back into the chat. I said cancel, I do not want it. I went thru the hoops to get in touch with another live agent in chat. She apologized said they would take the charge off. Then she offered to bundle a deal when I told her I wanted to cancel Xfinity Now. As she worked that deal out I said what I really also need is my Fedex Tracking number and to make sure the Series 9 watch is cancelled. She said it was but that they might still send it. Then a tracking number populated in my email. I asked if that was for my Ultra 2. She said yes. I said are you sure, you sure it's not Series 9. I made sure I explained all this to her. She said she was sure. I said if that is truly the case you have resolved me issue thank you so much! She asked me to leave a good review for her please. I decided to wait as I wanted to be sure the Ultra 2 really was coming. The next I spend the day tracking the watch to make sure I was home during the 10:50 - 2:50pm estimated window of time. After 2:50pm it updated to by the end of the day. I got back into the chat and talked to lady who ended up confirming what I feared. The Fedex was a the Series 9. I asked why don't I have the Ultra 2 coming year. She said it's still processing and that she could not tell me when it will ship. When I bought it, it said it was in stock. I am THOROUGHLY FRUSTRATED. I asked her if they can do something to make up for the headache and hoops and lost time. She said she could not but maybe I could call back to Mobile Care. I was already late taking my kids and their friend out for take out like I promised them. Also the Fedex that I was assured would come still never came. This has been one of the worst experiences I have been through. And even thought the chat people were nice, it felt like they were just trying to make a sale or tell me what I wanted to hear. They did NOT resolve my issue and I still have no idea if my order will come through. I have been charge $350 and I don't even know when my watch will get here. I would appreciate a manager or someone calling me and making this right.
