Been to EasLondon numerous times same guy that am suppose to visit again

What happen is he booked a return flights was suppose to go on Thursday to East London back on Monday morning we agree with finance and all forgotten that I've got bookings on Friday in Randburg whereby they've paid already

The moment I realised that's on Thursday morning I call him with no luck I then send him the message and explain to him that I can change dates and be liable for the costs the respond was just " THUMBSUP "
I thought that means it's okay
I go ahead with changing of dates to Saturday mid-day
Only later yesterday he calls me to tell me he's not gonna give amount hence I've changed days oh okay I understood that but he's gonna give only 50% like really and if I don't show up he'll just spoil my profile hence he's a GM "palmonmyface"

Not sure what to do BUT I now don't think it's gonna be a good session hence he's now not talking and my flight is now mid-day
I do have hotel's accommodation confirmation and all but no money as yet

Am so so confused to be honest.....

While you have a name to uphold you are also running a business. Consider the financial impact (now and any future income) between Randburg and East London. Also you are well known on ESA so what effect will a negative review or comment have, especially should you respond with an explanation? On the end of the day it is your decision...
