A scretary told me to leave a voice message to her boss, because he was busy at the moment when I dialed his office number.
So, I left him a message like:
Good morning, Mr.XYZ. This is Kitty Lastname. Kitty Lastname is my real name. I am not a machine. I am from the ABC cake shop, which is located a few miles away from your company. I tried to keep in touch with you but your secretary told me that you were very busy. Sir, you had left your XXX under the chair you were sitting...
My teachers used to tell us never use "I am" on any phone call conversations, so I am very not sure whether I was wrong to say "this is" and then "I am" together in the above voice message.
Please help me.
