MANILA - The Department of Trade and Industry on Friday said it would "closely" monitor the development involving Shopee's meet and greet incident to ensure aggrieved parties are compensated.

More than 116 supposed winners of the Blackpink promo were not allowed entry to the meet and greet area despite being notified by the online shopping site, the DTI said.

At least 10 complaints have been filed against the e-commerce site, the agency said.

"Aggrieved party must also be compensated and it was reported that Shopee is now talking to each aggrieved party for compensation and rectification. They should have a program to settle all complaints. We will watch this closely," Sec. Ramon Lopez said in a text message.

Under the promotion's mechanics, the top 586 spenders from May 11 to May 25 would have the chance to meet the K-pop group BLACKPINK. Consumers claimed that Shopee changed the mechanics on the last day of the promotion.

Such changes, if proven to have been committed, "is a violation" that requires a penalty of up to P300,000, Lopez said.

“It turned out marami pala siya, nagkapatong-patong yung mga unang nanotify. Hindi pala sila pasok sa 568. Kumbaga may mas mataas pa," DTI-Fair Trade Enforcement Bureau director Ronel Abrenica said.

(It turned out there are a lot of them. The people notified piled up. They did not made it to the 568. There were those who ranked higher)

Officials of Shopee were summoned Friday by the DTI-Fair Trade Enforcement Bureau. The case is currently being investigated, Lopez said.

Shopee earlier apologized for the incident by saying they were reaching out to those involved.

In an interview with DZMM, Lopez said preliminary investigations showed that Shopee might have experienced a “system error.”
