Dishonest Marketing

I booked a flight to London a few days ago on eDreams. I received an email to state that the booking was confirmed. The ticket was about R13,000.00 and was a return ticket between Virgin Atlantic and Air France. I proceeded to book accommodation and then two days later eDreams informed me that the booking was rejected by Virgin Atlantic and consequently my booking is cancelled. I received a refund and advised to book again. When I tried rebooking the system indicated an error. I tried booking via Emirates on eDreams where the price was eventually R5,000 more than what eDreams showed. Because of this company's lack of diligence, I have now had to book another flight I could find which cost me R20,000.
