Select Portfolio Servicing, a mortgage servicing company.I had a mortgage with GMAC Mortgage for years, was very happy with the service I received from them.I was late a few times and my mortgage was bought by Select Portfolio Servicing. Not a very professional company. When you call they are very short with you and border line rude. If you are one day late they are calling you. I thought there was some kind of grace period. I guess not.
