The rep should be able to guide and educate you in your options on how to rollover your funds. Also in particular how to recover your withheld taxes. They are equipped to do this since it is their profession. Much of it will just be what many of us are sharing. But talking to a person over the phone and having them be your side to have a shorter feedback loop can be what you need to get this done confidently.
