SINGAPORE: For Mr Terrence Chong and his wife, coming home after a long day at work was no longer a simple pleasure. Instead of relaxing, they were met with a growing pile of mysterious parcels on their doorstep.

Throughout two and a half months, the couple received daily deliveries of empty or wrongly labelled packages—none of which they had ordered.

According to CNA, Mr Chong, a 46-year-old educator, suspected the parcels were mistakenly sent to their new address. They had only moved in a few weeks earlier, so they checked with the previous owners.

Growing concern for e-commerce platforms

Shopee responded by banning the accounts of the sellers and buyers involved, halting the delivery of any further parcels to Mr Chong.

The company assured the couple that their personal information was secure...
