I have a UPS account with negotiated rates that I seem to have successfully added to my SHIPSTATION account. The negotiated rates do show and everything looks fine until I select the option to print the label, I get the message that says: "Missing or invalid shipper name"
I have not been able to get SHIPSTATION to respond to even one single e-mail or phone call. The customer service for ShipStation has been deplorable. Please advise. I need help.
