XB8 Modem doesn't work with Xfinity App- customer service lied to me repeatedly

Now this going to be quite the post, so be prepared, especially Xfinity reps and the company! 

So, a little bit about myself my husband is a general contractor and electrician, we have been flipping houses since we were 19 years old and his dad was also a general contractor who flips houses. We are 37 now and continue to do the same to this day. I do the work right along with him and the business is in my name. I also work in tech, to say the least we understand how all of this stuff works. Lol. We have had Xfinity aka Comcast since we were 19 years old and I have used Comcast since my parents had it honestly. Needless to say I've had a lot of experience with this company and it's had it's ups and down, but this has been the WORST experience in my 18 years of paying for this service. Which we all know is very expensive and has definitely increased every year. Recently, I upgraded to the Storm-Ready WiFi and the XB8 modem, so the newest model to my knowledge. I received it a couple of weeks ago, but finally had time to install it on Friday ( June 28th, 2024) just to be specific for the Xfinity representatives who read this post. Installation was simple, hence my work experience. Then on Saturday I went to activate the Storm-Ready WiFi and you do all of this through the Xfinity app as most of you know. Just to mention my husband and I have 4 kids, yes I know, it's a busy household and we have lots of equipment, so we pay for unlimited Internet and Xfi Complete. Well, the activation process was taking over an hour so I used the chat service to find out what was going on. This is where it gets terrible! I finally get the robot to get me to an agent, who lied to me repeatedly and I asked to be transferred to a supervisor because what he was saying didn't make sense. An app issue wouldn't be connected to a tech problem. The next person repeatedly lied to me again and I asked to be transferred to a supervisor from a different area. Well he said yes and then came back and said the word she. I immediately said wait, you know who this is already? Then he goes "he uhhh she or he." It was a she on the phone. During the call about 3 minutes in I got another call from Xfinity and they told me to hang up. So I did and that didn't make sense to me either. This "supervisor" who literally talked so slowly to first mention she was a single mom and her husband just died. It was so uncomfortable. Then I just said listen I have been lied to for 2 hours now and I just want to get to the point. Her exact words "it's a tech issue", I just responded with I need to let you go and figure this out. I gave up and rebooted the Storm-Ready WiFi again and it worked. Which btw I said I would do several times because they never did a system reboot on their own and they refused. Which was odd too. At that point I fixed it myself and knew it must be an app issue. Then this morning I went back into the app and it said my main modem was down and my Storm-Ready WiFi was being used. After a simple search I knew my main modem was working fine. Again, definitely an app issue. So I went to Google, I found pages and pages of people saying the same thing, having the same issue with the XB8 modem not working with the app. Devices not showing up and other errors. I was sent a text about my front door sensor battery being low and to click this link to order complimentary batteries so I did it and of course the robot chat had an error and I had to chat with an agent. The lies started all over again, he said he ordered the batteries and gave me a confirmation number, then I said I would like to mention one more thing. I described what happened and that said is was a known issue and willing provided links. He denied it was a known issue so I provided the links and he transfered me. That rep then did he didn't order the batteries and would fix it  and then said they would transfer me to a supervisor who would credit me and fix the issue and that I will receive a confirmation number for the order. Well, this last person claimed to have ordered the batteries and apparently the order number was a date and time. When I said I don't believe it because it wasn't a confirmation number, he said he would send a tech to my house and he would make sure I wouldn't be charged for them coming. I immediately said no because I have no trust in Xifnity right now and that my contracts end in August and I will cancel my service at this point. He then disconnected me and I was sent back to the robot. That is how Xfinity customer service treats their customer who pay over $300 a month. Now let's all see how they respond to this or if this respond at all!
