Experiencing a SIM card hack

I’m currently dealing with sim card hack where someone got into my T-Mobile account pretending to be me and was able to have a Sim card swap authorized. Immediately they were able to start getting into many of my accounts. I eventually was able to get my Sim card back for two hours and put a sim card block on however the hackers changed my phone number to a new carrier - Verizon . It has now been almost 48 hours and I’m fighting with the two carriers to try getting my Sim card back with T-Mobile. It’s been a nightmare. It seems until I can get control of my Sim card this is ongoing. I called the credit card agencies and my credit card companies banks etc. of them all surprisingly credit karma is one of the worst to deal with but Venmo and PayPal have been pretty awful also. I change my passwords and lock my accounts and the hackers get back in and change them again and provide fake emails and phone numbers. I’ve been on the phone non stop for 48hrs and can’t seem to gain control of my accounts . Any suggestions?
