Review Update. I ordered and paid for 5kg DL-methionine from Cynthia Jones at CynthiaSales who saw my request for quotes on her Tradekey portal. Delivery failed and I was informed by seller and driver to pay extra into eWallet since they sent 10kg. I refused. They refused delivery until I pay up. I was offered less than half my money back if I cancel order. (Demanded amounts fluctuated continually) Both driver and seller appear to be extortionists who demanded extra payment. Suspected fraud. Order from 19 February remains undelivered by 18 March'24.
