I had a cell phone number for the past 10 years, but switched to T Mobile last year so that I could travel in Europe. Well, due to my forgetfulness, I didn't reload the number, and even when I emailed them about it around the time the account deactivated (to ask if I needed to do anything to keep it active) the guy was like "nope! All good!" So now that I'm going back to the US.... I learn I've lost my number. T Mobile isn't being helpful. They say it's been "donated" but they don't know where, or how to get it back. Is there a way to track down the number and get it? I don't think it's in use, though I haven't tried calling it yet. Someone else told me they called recently and couldn't get through. So... how can I get my number back? Thanks!
