The e-Commerce Association of Bangladesh (e-CAB) has suspended memberships of four e-commerce platforms, including Evaly and Dhamaka.
Two other companies are - Sirajganj Shop and Glitters RST World.
Earlier, e-CAB sent show-cause notices to 16 companies on 18 July following several allegations of fraud from customers and merchants.
"The four suspended members did not give any satisfactory response to the show-cause notices. They did not follow e-commerce guidelines and have not paid customers and merchants on time as well," e-CAB General Manager Jahangir Alam Shovon told The Business Standard on Wednesday.
The online platforms got the money in advance payments by luring people with heavy discounts on products on their sites and promising delivery in 7-45 days. Buyers, however, are yet to receive the items they ordered. Besides, the companies also owe huge money to their vendors.
Earlier in August, e-CAB suspended memberships of four more e-commerce firms, including Eorange and 24tkt.
