meu imei foi bloqueado na t mobile sendo que meu telfone é do brasil

Hello, gramps28. I would like to know if it's possible to obtain the date when a device was blocked. I am a computer forensic expert working on a case in Brazil where a victim of assault had their device blocked by an ex-partner. To build this case, I need to prove that the device belonged to the victim for a long time and that the block was an act of revenge. For this, I need to gather digital evidence, including the record of the blocking request. Could you please let me know how I can access the date of this request?

I greatly appreciate your cooperation and assistance in this matter.

Sincerely,
Perito: Jackson Zacarias
