Teacher, I am trying to improve my reported speech. Can you please check the paragraph for errors.
I telephoned Mr. Xing's office yesterday and spoke with Angela, his secretary. I referred her to our earlier telephone conversation a couple of days ago wherein I had told her that there was a typo in their Sales Manager's report regarding the date. I told Angela that we had taken another look at the report and we realized that the given date was correct. I apologized to Angela for the confusion.
