called and said his name is Samuel Adams with MRS Associates.

He called the other day from another number and today this one showed up.  He said he needed a decision from a girl today.  Funny he said that on Wednesday when he called.  I told him to contact her via snail mail and to stop calling here.  Glad I had read about this company online.
