Tradex continental shipping scam

Tradex was tasked to transport a golf cart to me from the Western Cape for delivery within 3 days. this delivery is overdue and delivery has not realized in almost thee weeks. They kept on charging me for Insurance, all kinds of forms along the way including the DA59 form. I have proof of payment for all. They refuse to communicate with me, and I cant call them. This is a scam - be careful
