好的,实在不行,就试着打个电话,她会原谅我的。I feel you are thinking about it too much. It is normal that you could not hear the employer name clearly on phone because they know you might send a lot of resumes and you could not be familiar with each names. I guess it should be okay to call them to ask more information about the position. It is impossible that they would cancel your interview because of this rediculous reason.
