I found out by chance from Yandex.Maps, as this is the nearest exchanger to the hotel. A couple of days before departure, the WhatsApp manager gave me the course and conditions. We arrived today, and the courier delivered the money within 30 minutes. Delivery is 200 baht. Everything went great!
I learned about the service, on Facebook, and from friends. I arrived, transferred money from the savings bank, and received cash baht. It is very convenient and fast, and the course is very profitable. Thank you guys for such a service😇
