What is the best way to begin a collection discussion with a debtor in Mexico?

Answer: I prefer: “Buonas días. No hablo español. ¿Usted habla inglés por favor?” [Translation: Good day. I do not speak Spanish. Do you speak English?]. All kidding aside, I recommend you greet the debtor, explain who you are, ask for a manager in their accounting department, and make a specific request for payment.
