Customs director-general Subromaniam Tholasy said his team was doing checks on the ground, but the best way to deal with the problem was for the people to keep a watchful eye on prices.
“Our enforcement officers are on the ground with Consumer Affairs Ministry teams to check on traders and services across the country.
“But we really need people to lodge complaints with us or with the ministry to put a stop to profiteering,” he told FMT after being asked to comment about a photograph of two receipts from a cafe-bistro that is making the rounds on social media.
The receipts show a RM7 difference for the same breakfast meal on May 26, with 6% GST, and today, with GST rated at zero.
The bistro management has apologised, saying that the error arose from changes to the billing computer software and asked customers to present their bill for rectification.
The first receipt for May 26 shows a total charge of RM51.70 for breakfast, juice and coffee, which included a 10% service charge of RM4.43 and GST of RM2.23.
The second receipt dated June 1 shows a bill that was RM7 higher at a total of RM58.30, including service charge of RM5.30 and excluding GST.
Subromaniam said his team and ministry officers were looking into the complaint, which was received earlier today.
GST was reduced to zero rating on all goods and services from today until the new Pakatan Harapan federal government reintroduces Sales and Services Tax in September to meet an election campaign pledge.
Tough for Malaysia to manage without GST revenue, says report
