Dube-Ncube said there were other cases which the consumer protection services investigated after complaints from consumers.
One is against Checkstar Supermarket in Phoenix where officials found excessive pricing of Savlon antiseptic liquid.
She said this matter has been referred to the police for further criminal investigation.
Dube-Ncube said there were allegations of excessive pricing on Lucky Star tinned pilchards and hand soap.
“This matter has been referred to the National Consumer Commission and Competition Commission for a non-compliance notice to be issued against the supermarket,” Dube-Ncube said.
She said consumers also lodged complaints against Safair Operations for refusing to issue a refund, but instead handed over vouchers after deducting a R300 cancellation fee.
“It has been explained that consumers should not be penalised in view of the national disaster announced by the president of the republic … Cyril Ramaphosa.
“In order to protect consumers from exploitation during this period of lockdown, the department has engaged the services of the Consumer Goods Scheme Ombudsman,” Dube-Ncube said.
She said the ombudsman has since issued a statement warning retailers and airlines of the consequences of non-compliance with the Consumer Protection Act.
