Welcome to the forum! Most of us are shoppers in the USA and Canada. There is an organization, the MSPA that is an organization of mystery shopping companies. The link is to a page that is for companies to find a mystery shopping company to do shops for them, but if you go down the page you will find that there is a company in Malaysia that likely has shops in your area. [
www.mspa-global.org]. You probably can google them to find out more about them and perhaps register as a shopper.
