NationStar Mortgage Given the Run around Dallas Texas

My loan was transferred to Nationstar in May 2013.  I have not received a Welcome package from them.  I had to call to find out where to send my payment to.  I have been trying to get in touch with them for over a week.  I first have to nagivagate thru options without being disconnect, second I have suffered thru 10 minutes or more hold time just to get someone that tells me I have the wrong department and I get disconnect.  I have been trying to find out why I have fee charges.  I haven't been late with my payments so I don't know what the fee is for.  Just think I was so happy when I found out that I didn't have to deal with my old mortgage company (Ocwen) just to find out that Nationstar is just as horrible.
