Hi, I'm calling about my pay.
Then say
- It's Alex, I worked at the branch.
- The payment due on the 10th hasn't come through.
- Can you tell me when it will?
- The account details are the same as before.
If they ask
- I'll check.
- Thank you. Could you call me back once you know?
- It goes out next week.
- Which day? I'll check then.
- We have no record of that.
- I'll send you the dates I worked.
Ending
Thanks for looking into it.
