Webuycars waste of time

After chatting to a salesman from Webuycars Port Elizabeth we scheduled a meeting for 10:00am Mon 20 Nov to view a boat I am selling. 10:00am came and went, at quarter past 10, I gave him a call and he said he would get back to me in 15 minutes. At 11 am I gave him another call and he had all sorts of long stories about this and that and rescheduling. What gets me is I have put my whole day on hold for a meeting with this man and he just blew me off with no regard whatsoever, wasting my time which I set aside to have this scheduled meeting with him not bothering to call or do anything about it, wasting half my day. I feel this is a very poor manner in which to conduct business. I then asked for his mangers number which he said he would text me which he also failed to do which has left me with a very bad first impression of Webuycars
