Number lock should protect subscribers from xfinity support

 I recently lost my phone that had an eSIM in it. I had number lock on my telephone number that I've had for 20 years. I went into the store to get a SIM card to put into my iPhone 7 to use as my temporary device So I can receive my calls and texts. The store had trouble activating a new Sim on my phone number because they said that there was some pending order and they were ready to close for the day so I had to leave. I did however get a new blank Sim and I called the 800 number in order for them to handle things and they made it even worse. They activated a brand new line with a bogus number as a temporary holding space and they tried to activate that and said that my old number would be overlay to that temporary number. My phone was never able to activate not even with the temporary number. They canceled my other line that had my original number 8612 on it and I got an alert to call the number immediately if I did not cancel that phone number. I called and then I got to run around that they were retrieving it and a call back in the next day. Now I'm told I can't get the number back because it was a lost phone and that it wasn't documented appropriately therefore I have to use a new number. I still don't have service regardless on any number and my phone number of 20 years it seems to be gone and I've spent seven hours on the telephone and in the store etc. I'm trying to get this straightened out this is ridiculous this is really unacceptable. I have no idea what they were trying to do by adding a new line when it was a simple activation of a SIM card on a current line and deactivation of the eSIM on the device that was lost. I presented my drivers license and my credential at the store and I also did all of the stuff on the phone that needed to pass all of the security measures. I'm very frustrated. Ready to drop everything cable Internet telephones cell phones because this is one that they don't seem like they know how to fix. Anything can be fixed if you try and get the right person that knows the process I apparently I'm getting people that have no idea and the saga gets even worse each time I talk to someone. Thank you Xfinity I've been a customer for 40 years. Maybe that number lock feature should protect them from their own mistakes so that they cannot just cancel the line and the number go into limbo to be reused by someone else. I thought that was the point of the service is to protect the number
