Fraudulent activity by a TMobile employee switching my SIM # to a new device to steal funds

Gosh, that's a nightmare of a situation especially considering you may not be able to get those funds back from coinbase. I know that with every day passing you need more answers. Unfortunately, this is a situation that only our fraud team can handle. I hate to repeat the same info you've been given multiple times, but we have to allow the fraud department to research what exactly happened which will determine the outcome.
