How are they working in Singapore? They are not providing or competing with locals on an existing service.
If I hired their service, a Malaysian based 'company', they bring me across to Malaysia, and I pay for their service when I am in Malaysia, then how are they working in Singapore?
Their vehicles travelled to Singapore legally, they have to pay for whatever tolls or charges that is required for Malaysia cars coming into Singapore.
Their service benefitted a lot of Singaporeans who travels to Johor frequently.
It's the same as those curtain companies in Malaysia who send their workers to Singapore to measure the Singaporean customers' homes, make the curtains in Malaysia, and then transport the curtains back to their Singapore customers. Are those consider as illegal working as well? Shall those be banned also?
