Do NOT deliver

We had a urgent package sent to us from UK, given over to TNT by Parcel2go. I have an account with TNT, I arranged with them to please treat my package as urgent, I will even collect from the Pretoria branch I said, before any problems arise, please let me know. By Friday morning the package was in JHB, I phoned and asked if delivery would be possible, no they said we must first pay the duty's. I asked to send me the invoice I will pay immediately. No invoice was sent. Saturday closed, Sunday closed. Monday morning I phone and ask for the invoice, Sandra said the package will be delivered COD. Monday no delivery. Tuesday we phone, they tell me the package is held because of non payment!!! We tell the guy what Sandra said, he says he will send it. Checking the tracking, still not sent. What is wrong with this people?<br> Up to now, no package, I refuse to keep on phoning and begging. TNT has done me in before, and I am getting used to the bad service TNT promotes.<br> When will I get my package, my urgent package that has now landed me in serious trouble with my customer.<br> Really TNT, shape up!!!!!
