Applied for PhD but got admitted to an Ed.M Instead

[naomi6]

I'm completing my MA degree this Spring Semester. I applied to a few Doctoral programs in the field of education. I recently received an acceptance letter; however, it is to a Ed.M. program which I did not apply for. I find it strange that I was considered for the Masters program when 1) I checked no on the application for consideration into the master  program and 2) I'm currently completing a Master program.

 

Why didnt they just reject my application?

 

I can't fanthom the idea of spending another 2 years for another master degree... plus the cost (My current school debt is $40,000).... It took me three years to finish my current MA program (attended part-time due to full time job)....

 

The school I'm currently attending doesn't offer doctoral degrees in Education.

 

If i was to attend the Ed.M., will i increase my chance of getting into the PhD I initially applied for?
