Like I've pointed out to others, I have nothing to say about other companies. I speak only about this one company where Rachel claimed that it would cause turmoil if you attempted to transfer your number out.
Rachel didn't actually raise a request for number transfer, so this was conjecture. I've gone through the process, and it was smooth. That's why I think it's a mole hill.
Everyone is saying "yes but at other companies...". Sure. I concede that. Just not at this one company.
