Rain refusing to provide ITC number

I'm extremely frustrated and disappointed with the service I've received. My phone was ****** on January 12th, and I've been going back and forth with Rain to obtain an ITC number, which is required for me to file an insurance claim.

Despite their claims of assisting with a SIM swap, this is not the issue at hand. The problem is that I need the ITC number to proceed with my insurance claim, and Rain has failed to provide it. They've mentioned sending a confirming letter and blocking my phone, but it's been two weeks, and I've yet to receive anything.

The lack of communication and incompetence I've experienced is appalling. To make matters worse, I'm still using their WiFi services, which is unacceptable given the poor service I've received.

I need the ITC number, and I need it now. A service provider claiming they cannot provide an ITC number with no reason does not make sense, and wanting to replace this with a supposed confirmation letter—where is this so-called letter?
