Tshukudu trailers - very unprofessional

Bought a diesel bowser, collected from supplier, asked if they could test they say all in order. Get to site, fill diesel, and there are leaks from the spout and the filter. Call the supplier, Pieter, whom says he will come sortout as soon as the correct filter arrives. A week later he says I must bring the bowser all the way back to his yard for remedy the problem. I explain that I cannot as we busy on site. He then keeps on dodging and says I must bring it or it won't be fixed.

Very unprofessional and unfriendly after I spent R40 000 or so on the unit.
