Incorrect communication, and wrong information displayed on check overhead display! Allowed to

Booked a flight for the very first time with FlySAFair on March 1, 2019 for departure on March 3rd, 2019 from CPT to JHB 17h00pm flight (F127). I arrived at the airport an hour before the time, checkin online at 12h00 pm on they day but realise that you need to be at the airport to check the information boards that will provide you with details of which gate you will be departing from. Your boarding pass clear say the following under the Gate heading;" Check overhead displays" to see your gate number. At that point I went through and to my surprise the flight was delayed and further update will be 17h55. Which was the time that my flight was suppose to depart.

At 17h55, the info overhead display board still shows that delays and further update will be at 17h55. At 18h00 pm, the message changed to" Departure 18h15pm. I eventual run to the gate which was not far since I was less that 20 meters away and to my surprise the flight left. It seems that they send sms, some people receive their sms at 17h55 pm but gates was closed at 18h00pm and flight left already.

After complaining about the bad comms, the Day manager comment was "we did sent out a sms but I did not receive an sms, because my booking agent insert my number incorrectly. The following comment was, "We don't control the boards, but I wonder who provides the instructions. No solution was provide and alternatively I had to catch a flight the following day...which was totally inconvenience.

SIES FlySAFair, I shall never fly with you again. It was my first and my last even if you are cheaper than the rest........!!!!:( Stop passing the buck and provide solution because customer pay upfront for your disaster!!.
