Beware of Global express logistic

My first experience with Global express logics out of Upington was with the delivering of my trailer that I bought from Silverton trading they started by saying I have to pay them R10000 as a insurance then later onR5000 more for a municipal inspection after that R3500 to get a driver and to finish the order all the way promising that all money will be refunded this afternoon I got a email from them saying they need R5000 more to get the order out the door if I do not pay the money the orber will be canceled and the R18500 that's been payed by me will be lost and the process must start over on a other date
