Delayed Invoicing

I requested Zante to send me a Tax Invoice and Statement so that my employer can make payment for a training course I would like to attend. From early on, I stressed to Zante that as our Financial Year-end is approaching, it is urgent that we receive the invoice and make payment. Even after indicating my email subject line as ***URGENT***, 4 business days later I am still waiting for the invoice. Does the word ***URGENT*** not trigger anything that says quickly, important, etc?? I also stressed from early on that if I do not receive the invoice soon, the PO will unfortunately be cancelled.<br> <br> PATHETIC SERVICE!
