I had problems with multiple paid orders because the sellers were simply unprofessional (e.g. Wrong shipment, no shipment, cancellations without notice), all in less than a week. I complained to Lazada's customer and expect they'd at least advice these sellers to do their jobs right and fulfill the orders. Instead, I was told that my only option is to negotiate with the sellers. If anyone is thinking of buying from Lazada and think that Lazada will stand by them if they encounter problems with the sellers, think again.
