Tina, this is an online help forum. We aren't associated with any HR department at any company. You didn't state what company you work for either. My suggestion would be to call your HR again. Maybe talk to someone in your office about who to contact.
You should also try the investment company that manages your 401-K. If you are working with a financial advisor on the rollover, they should be able to help you figure out the correct person/company to follow up with.
In addition to Leah's point, if you already have submitted your transfer paperwork sometimes the receiving counterpart can call the delivering entity to inquire on the status of the transfer.
