Misleading advert

The company sent an email saying that there will be a special on the 21st of June , I waited the whole night for 00:00 kept checking the ticket to change the price as the ad they sent was saying ticket will be R1400 From CPT- ESL. The ticket never changed it was holding the same price as previous day.

They wasted my time and couldn't function properly at work because I did not sleep waiting for the misleading advert which never happened , I eventually booked with the same money as it was on the 20th.
