Hello!
Is Petti there?
I'm sorry, I'm afraid you've dialed the wrong number. There is no Petti here.
Wrong number? Are you sure? I called yesterday and she was there.
I'm sure you have the wrong number. This one has been my number for more than 20 years.
That's impossible. I remember the number clearly. Isn't this 763-4565?
No, It isn't. It's 736-4565. It seems you've misdialed.
Really? I'm so sorry I bothered you. I'll try again.
That's all right. This sort of thing happens all the time to everyone.
Yeah. I guess it does. Sorry again for bothering you.
