Which of this is correct when calling concerning a job opening:
Hello Mrs Goodman. My name is ..... and I'm answering the advertisement for a ..... that was in ..... paper."
Or
Hello Mrs Goodman. My name is ..... and I'm calling concerning the advertisement for a ..... that was in ..... paper."
I saw the first example (the one with answering) on a website but it didn't sound right to me so i decided to create this thread to get the opinion of other members on WR. I would really appreciate your response. Thanks
