They do not seem to have a customer service team

Customer service is almost non-existant. The only way to reach them is via Whatsapp, and it seems they have perhaps only one or two staff to deal with requests. I've been waiting to hear why they charged me twice for a UPS, and trying to get a refund. Start time of chat: 13:11, status of chat as of 15:53: "Hi, Willie-the-bot here, I'm still trying to put you through to one of our Live Chat agents, they'll message you as soon as they're available. If however you'd prefer to cancel the Live Chat request, simply type ENDCHAT."
