Still waiting

On the 29th of June I booked a ticket for my mother from South Africa to Dubai to visit meon travelsart.co.za I accidentally spelled one of the letters in her name wrong realizing that after the ticket was purchased. The travel agent from Travel Start told me that I have to buy a new ticket then they will cancel previous one and I will be refunded within 6 weeks.

2 months later I contacted as no refund has been made which they told me that the airline did not sanction the email and that they have to send the details again meaning in the 2 months they never checked if the airline received their documents and is processing it. They told me they will follow up and expedite it. I am now going into the 3 month and they never pick up their phones or respond to my 6 emails I have send so far,no response at all. Their website state the refund process and period and this has not happened at all. It isnt small change and I re**** on the refund for other purposes. I left one letter out of her name and the date stayed the same and even paid R3000 more for the new ticket which was fine and not the issue
