Victimized by SIM card swap scam; would like to engage T-mobile regarding aftermath

I just want to say that the SAME THING HAPPENED TO ME. I was sleeping one time when I was getting T-mobile text alerts to approve the sim swap. I denied it twice and called Tmobile right away. The 1st representative told me someone is in the process of getting "their number back" and asked me if I wanted a new number. I SAID NO. He said he will handle the situation and we ended the call. Immediately, I lost service and had to call with another phone. By the time I called the second agent, my AMAZON, BANK, AND PAYPAL HAVE BEEN COMPROMISED. The first agent as not able to stop the sim swap but the second agent restored my number back to me. THE FACT THAT THIS CAN BE DONE SO EASILY IS SO WRONG. I have no idea how they were able to collect to much data and how they were able to impersonate me. I did change all my passwords but exactly WHAT INFORMATION DID THEY HAVE ON ME TO BE ABLE TO DO THIS? THIS COULD HAPPEN AGAIN.
