Sold trucks under false pretense

I bought hineysucker trucks from this company, upon delivery two of the trucks were water tankers and only one was a hineysucker. The one which was a hineysucker had a faulty sucking system and the promised that all three trucks were tested prior to delivery. Since Monday I have been in communications with the sales reps and the workshop manager of the company to no vail I ended up requesting to speak to the owner and they refused to give direct access. As I am writing to you the trucks are supposed to be providing a service to my client but the are not suitable for the job. The arrogance of the workshop manager by the name of Naas and the refusal to take responsibility is of monumental proportion. They at some point referred me to a gentleman named Chris as they claimed he built those systems when the gentleman told me that he did not build those systems they then referred me to a different gentleman for the same thing and of course this gentleman distanced himself from those trucks also. I happen to have a friend who had a similar experience with this company unfortunately I only knew of his experience after I had bought this garbage from Country Wide Truck Sales.
