This number is Sally Mae. It is a student loan company, this is an automated call, if you or someone at your number has recently started a loan consolidation application then they are going to call. The reason is because at the end of this month (July) student loan interest rates are going up, they just want to get you in on a plan that way it will save you some money...but be careful because they are a loan company not all of the options they will give you will be the best. Make sure you look into all of your options and investigate them for your own sake, some of the options are better for them and wind up making you pay more money than you have to, but some have to because of their money situation.
The reason I know is because my husband has loans through them. Hope this will help some.
