Unprofessionalism and rot

I reserved a food trailer from webuycars Dome, and paid the reservation R5000, this morning I hired a bakkie to go tow my trailer. The excitement when I saw it turned to the highest level of disappointment, disrespect and unprofessionalism. I felt like a complete idiot when they told me my trailer has been sold. How do you sell someone's asset reserved for purchase without even notifying me. This was gonna save a lot even if I was contacted, I was gonna save myself from skipping work, hiring a bakkie and driving all the way for nothing. I'm really disappointed and feel how disrespected we are taken, when the management or staff friends with deep pockets are sold our things, by bypassing the systems or getting bribes
