DISGUSTING SERVICE AND CANCELLING OF WHOLE BOOKING

I cannot believe the absolutely appalling service we are receiving from travelstart. We booked flights in June going to Serbia. When we did our covid tests I tested positive so we unfortunately had to postpone our trip. When we were ready to re book our flights we asked for a destination change. We received an email and a WhatsApp. The email stated the date and the new destination. On the whatsapp the person asked us if we would like to proceed as per the email sent, we said the date we wanted to fly was the 23rd Sept and not the 22nd Sept. The person said fine she will make the changes and then send us a payment link for the admin fee for the changes. We received the email and clicked on pay. When we were finished paying the confirmation came up and the destination was still the old destination. We have sent emails to the complaints department and send numerous whatsapp messages. We have been told we need to pay another R 1000.00 for the change. We did not make the mistake the employee did. Now we received an email that stated that if we do not make payment today we will loose our whole booking. We cannot get hold of an actual person to get this sorted and no-one is getting back to us. We are now so frustrated and our now requesting that our flight that we originally booked be refunded to us, including the change amount. This is absolutely disgusting business practise and no-one at travelstart seems to care.
