I've phoned 6 times already and still no invoice

My package arrived at TNT Maitland on the 22nd of September, I have phoned 6 times since then and every single time I was placed on hold for 3-4 minutes and then someone at accounts answers.<br> <br> Every time I get told that they are generating the invoice now and they are sending it to my email address, which I had to give every time. I've received no emails for invoicing and this situation is rather frustrating.<br> <br> This was a time sensitive package as part of a analytical report, so we had to incur other measures to have the same samples shipped via Fedex and it arrived today and was sent on Friday?<br> <br> We also did not have any duties/taxes or charges since it is a analytical sample.<br> <br> We will certainly refrain from using TNT's services again.<br> <br> We would advise the same for other companies.<br>
