Do further due-diligence before purchasing (i.e., references and previous customer contact references and check with the foreign governments on scamming reports).

On 12/15 we sourced this company as a distributor of electronic components. On 12/16 we received a quote and engaged in a purchase contract by giving the company a PO. On that day, we received their proforma invoice and on that day, payment was remitted. We were told the order would ship in 2-3 business days and after several attempts in trying to obtain tracking, no response has been provided by the seller. We also tried to call them several times.
