Booking not found when checking in at Airline at Airport - no assistance from Travelstart

Travelstart's service is one of the worst I have ever dealt with. There is no way to contact them telephonically or to hold someone accountable. On the 27th of December, I was left stranded at the Port Elisabeth Airport due to Travestarts incompetence. I changed my flight from the 02nd of January to the 27th of December 2021 from Port Elisabeth to Johannesburg and kept my return flight from Johannesburg to Cape Town. However, when I arrived at the airport, Airlink could not find my reference number for the flight. The Airlink manager even tried to edit the flight details and could not as Travelstart locked that reference from their side. I tried contacting Travelstart via the Whatsapp number and got no feedback (no direct line). I was then forced to purchase another ticket at Airlink at the airport to fly on the 27th of December. The situation was highly nerve-wracking as I also had my 18-month baby with me.

1st of January - I emailed Travelstart with all the required communication: E-tickets for booking and payment for flight with reference number booked through Travelstart (the one Airlink could not find) WhatsApp conversation (The request for urgent assistance etc.) Newly purchased tickets from Airlink for the 27th of December 2021 and return flights. Requesting a refund of R 3881.50 for the ticket, which Airlink could not find when I tried to check-in at the airport - I got no reply to this email.

5th of January 2022, I sent them another email requesting an answer and assistance. Finally, on the 8th of January 2022, I got their automated email informing me that they would get back to me as soon as possible.

10th of January 2022, I sent them another email requesting feedback and that my R 3881.50 be refunded. - Travelstart rep**** on the 16th of January, stating that my booking had been escalated to the relevant team.

17th of January 2022, I got an email from a support Travelstart consultant stating that he had tried phoning me and had not gotten a hold of me. I have no missed calls on my phone. Still, never the less I requested that the consultant phone me the next day at 9:00 AM and provide him with the cellphone number in case the one he has is incorrect - I have not received any calls from Travelstart to discuss the incident, nor have I received the refund due to me.

18th, 19th and 20th of January 2022, I sent the consultant and Travelstart more emails stating that no one had contacted me and that I needed this matter resolved - I finally got an answer on the 20th of January 2022, saying that they apologise and that they escalated the query to the relevant team.

Airlink has been in copy in all of my emails, and their service has been excellent. But, unfortunately, there is nothing Airlink can do from their side as the booking and payment were made through Travelstart.

I am shocked at the level of service and how they do not have a person/call centre on standby for situations such as my own, where a person is at the airport and can not check-in or board the flight due to a mistake made Travelstarts side.

I am unsure what to do as they have my funds, and no one is assisting me to resolve the issue, and I need the funds reimbursed.
