Unhappy and disappointed customer

Kindly note that I am very unhappy and dissapointed in the service received with your agency. My mother booked a flight for me on Friday for this coming Friday 23rd from Port Elizabeth to Durban when I went on the Flysafair website to check my booking as i had concerned that i didn't receive any confirmation SMS it displayed that "booking cancelled" of which confused me as i had bought the ticket the day before. I then tried calling the number on the slip and seemingly the office is not operational on weekends asked to be transferred to the emergency services with no luck. Today i called and the lady (Phumeza)told me that there was a problem with your system on Friday and now the flight is fully booked, I need to be on that flight on Friday and I honestly cannot be inconvenienced in this manner. Had i received this information in time i would have made a booking on another agency or through the Flysafair website itself.

I honestly cannot take this as an excuse, can this matter be escalated and I am not willing to take the 7 a.m flight that will connect from East london and only get to Durban at 17:00, i have meetings until 2.

Kindly treat this matter as of urgency, I need a solution ASAP.
