Utterly disappointed by the lack of Urgency and how travelstart deals with their clients

I booked two flights for my staff at 18:30 on the 30th of October 2025, but the times booked were incorrect, thereafter I called SAA directly to change the flights which I was then told to speak directly to Travelstart. This was at 18:50, called Travelstart customer held on for 12 minutes and my call was then dropped because the time had gone beyond 7pm which is the operating time. I could not send an email for someone to assist me because there is no email address. Awoke this morning to call at 7am which is the time they open for trading spoke to an agent by the name of Mpho who informed me that it will take 30 minutes for the escalation to be responded to, mind you the scheduled flight was for 9am. Did not hear anything from Travelstart I then called again at 8:10am when I was then engaging with another agent, told him my story and again I was informed that they will respond upon his escalation within an hour. Again no response from Travelstart, I opted to call again at 11am this time I got a hold of an agent by the name of Lisa who then told me she will escalate, whilst on the call she then informed me that someone has started working on the booking by the name of Siyed. I dropped the call and after 1pm I received an email stating that I now have to pay an extra 2.5k on top of a 2k that I already spent to book the flight, of which I refuse because it was cheaper by R500 to book on an airline directly. I then called Travelstart again to cancel the flights and request a refund whilst I was on the call with another lady the cal was mysteriously dropped by the agent. I called again and engaged with the 1st agent that assisted me in the morning Mpho, to request a cancellation or partial refund to which he informed to that he will escalate the matter. At 2pm I received an email informing me that I will not get a refund cause the ticket isn't refundable. I run a business, and I have been utilizing travelstart weekly to book our business trips for years and I am utterly disappointed at the lack of urgency and also how my case was managed by Travelstart. This is not a good reflection on businesses that support travelstart as much as our business does. I will never use Travelstart again even if it means paying a little extra.
