Xfinity canceled my account without my knowledge.

Yesterday, 09/26, my husband came in saying the xfinitywifi hotspot wasnt working outside. I tried to fix it. Nothing helped so i called xfinity customer service. I happened to look in my email and it says that on 09/25, I got an email saying "thank you for choosing xfinity" thanks for joining. Joining??? I've been member since 2023. I am a currently a gold member with you guys. So why am I getting an email saying im a new customer? With my exact email that is already in the system. I called customer service and they said it was a "coding error" and it should take 24 hours for it to work. He said that there mustve been a glitch in the system. It has been over 24 hours and the xfinity app still says my account is INACTIVE. I PAID MY BILL!! i have 2 very small kids at home so I cannot afford to lose my internet. At first, I thought it was the internet essentials plan expiring? But the representative said that wasnt it. That the plan was still on my account. Im not sure what is going on but I dont want my internet to cut off randomly. I have screenshots of everything. I just really need to see if this is someone fraudulently opening an account in my name? The representative didnt help at all. And I really, really need to know what to do next. Please!!
