The setting up of the Do Not Call Registry was a good move to prohibit companies from sending marketing messages to Singapore phone numbers.
However, there is a need to stop sales promoters from making door-to-door visits and from accosting people in public places.
Marketing personnel who call people on the phone will not know where an individual lives, but that is not the case for door-to-door visits.
I get at least 10 visits from sales promoters every month, even after 9pm.
Sales promoters should also not be allowed to approach people in public places such as MRT stations and shopping malls.
They may be allowed to set up booths at such places, and the public can approach them there if they are interested.
