Extremely bad service

My wife and I booked at trip to Cape Town in November 2020. Due to the curfew we decided not to travel. Travelstart agreed to keep the tickets open until April 2022. We have decided to go to Cape Town in September from the 13th to the 17th. I then contacted Travelstart via the contact form to advise them we would like to book flights for this dates. We were initially booked for the 6:30 AM flight on the 13th of September and 15:20 PM flight on the 17th (Not sure the exact time). I then received the e-ticket and proceeded to check the app. The app stated my ticket was suspended. I then filled out the contact form again. This is extremely frustrating as I cannot pick up the phone and call a Travelstart consultant. I received a response stating the the flight had been cancelled and that I should contact the Airline. I was never notified by the airline or Travelstart of the cancellation of the flight. I then proceeded to contact the airline and they confirmed the flight was cancelled and I was told to contact Travelstart. Once again I filled out the contact form and also asked to be called to have this sorted out as it has become very frustrating. I was called on Saturday 31/07/2021 by Anele and she advised there isn’t anything she can do but she would escalate it and someone will call me on Monday 02/08/2021. Today is 04/08/2021 and I still haven’t received a call. My tickets have now been changed to a different time slot of which I did not agree to. The only email address I have is for Lindsey Hartzenberg. I have sent her an email to ask for this to be escalated, I still have not had a call back or response. I need this sorted out ASAP. I need to be on a flight to Cape Town between 6 and 6:30 on the 13th. I am very frustrated in how this is being handled and what the status is. Please can a team leader or manager call me ASAP to get this sorted as this is just ridiculous.
