Mobile lines mixed up with unknown persons account and can’t get my lines back yet

I have been dealing with this issue since 6/1 with no resolution. My son’s phone screen stopped responding to touch, we decided it was time for a new phone. When we went to Xfinity store we were first told we didn’t have an account, untrue as I have confirmation emails stating we are paying our bill on autopay and when the payments come out, I also have a total of 5 phone lines. After taking the Iemi number off my phone the agent was able to determine that somehow my 5 phone lines were moved to another individuals account without my knowledge or permission. After doing more research it was determined we needed to call customer service. I spent over 3 hours on the phone trying to get our numbers back on our account, even ended up having a conversation with the customer whose account our phones were added to who said she had also been trying to figure it out without getting anywhere. Xfinity has admitted this was done by “accident”  by someone in their back office and that it happened in December of 2025. After talking with the customer whose account our numbers were transferred to and the customer support agent we were told they would be able to transfer our numbers back to our account, only to find out at some point Xfinity suspended our account and can’t transfer the lines back without creating an ECM ticket and documenting everything. I was told that the back office support would be working on the issue. The next day I called back and spoke with another rep and they told me that the ticket was being worked on and that there was an estimated completion date of Monday 6/8 which is a week away from when we first have been trying to solve the issue. I have spent numerous hours on the phone and still have not had the issue fixed. My son is still without a phone because we can’t activate a new phone and can’t even get his number that he currently has on a new phone even if we were able to get one. Xfinity then called me on 6/6 and the rep asked if our issue had been resolved, it was as if I was having to start all over again only to be told again they are working on the issue but there is not a resolution as of yet. I am beyond frustrated as Xfinity has no problem continuing to take our money for our bill yet can’t fix an error they caused and have no fixed. I just want my account fixed and I want my 5 phone lines back on my account. We have been customers since 2018 but this issue has been a nightmare and is making me loose faith in Xfinity. It’s completely unacceptable to make a jump through hoops to fix a problem that was caused by the company in the first place.
