Horse before the week ends

I've just received the strangest phone call ever.






Phone rings.
"Allô?"
"This is (so-and-so), do you need horse before the end of the week?"
"Huh... Sorry? And you are...?"
"This is (so-and-so). Do you need horse before the end of the week?"
"Horse?"
"Yes, don't you need any?"
"I... think you've got the wrong number."
"Is this not (some phone number)?"
"Nope."
"Oh, sorry sir. Bye!"

Hope she finds the right number or some unlucky person will not be getting horse before the end of the week. Whatever that means.
