Consultant did not return to me after promised

I went to the Sandton city branch for a quotation, the consultant quoted me two completely different prices within 5 minutes (about R6000 vs R8000) and insist on due to the nature of the business?!?! I am aware flight ticket prices do fluctuate but I don't think it would be from R6000 to R8000 in 5 minutes for the same class?<br> <br> the consultant told me that I have to bring a proof if I can find a flight quoted cheaper than what they can provide. I have done that, sent them an email and phoned a consultant. She provided that she would get back to me after asking her manager.<br> <br> After 2 days, I have got no email reply nor a phone call.<br> <br> I got my ticket elsewhere now, and don't think I'll be interested to go to the flight centre in the future.
