I paid on-line at costco.com for a mattress that has been lost. I received a tracking number from Costco for Ceva (a 3PL). A week later the Ceva web site still does not show my shipment. Coscto.com customer service cannot get through to Ceva and Michelle, the customer service rep, will not hold for more than 5 minutes due to a "company policy" that if not followed "I will get fired." I was told I would have to wait 3 days for another internal Costco dept. to investigate the problem once they read the email that Michelle will be sending to them. Still no answers about where the item I paid for is, nor when Costco might know.
