Ticket change troubles

I have used Travelstart for a number of years and have always had a smooth and positive experience to the point where, prior to 2020, even my international travel was booked through them. I purchased a ticket to celebrate a friends 50th birthday in Cape Town but due to Covid19 and national levels, the event was postponed. I made contact with Travelstart via the WhatsApp (no longer a telephone contact line that links one to an actual individual), with a response that my ticket was valid for a year. not having had a date, I was under the impression that when the time came, I would be able to activate the ticket. Alas, this was not to be. The automated responses on the WhatsApp are most appalling, with no concerted effort made to help the client. I was told to contact the airline that had no reference of my booking. Sadly, the event took place yesterday. I was not only unable to attend but also have lost the ticket and have not had a word back from Travelstart. Be rest assured that you will not ever have my patronage and while this might not affect your company, your service certainly affected my life.
