BUDGETAIR USELESS GHOST AGENT

On the 16/08/2015, I received my e-ticket from Budgetair South Africa for a flight from Cape Town to Johannesburg on 11/10/ 2015, reservation number: ZMHL7L. On 24/09/2015, I sent an email to BudgetAir (the only means through which one can communicate with BudgetAir), requesting to change the flight to 5/10/2015. I also indicated I wished to purchase a ticket for my husband. On 26/09/2015, I received a response from BudgetAir stating the change in price etc. On 1/10/2015, I responded agreeing to the change as indicated and requested (again) a ticket for my husband as well. Finally, I received the reponse on 5/10/2015, indicating that no seats were available (unsurprisingly).I had to book a return ticket back to Johannesburg on 5 October through another carrier as a result of the delay.Nonetheless, I felt I could still amend or cancel the ticket which still remained booked for 11/10/2015. On 7/10/2015, I sent an email again requesting a monetary voucher for the value of the flight. On 10/10/2015, Budgetair asked whether I wished to cancel the flight. I responded on the same day that I definitely wanted to cancel the flight. I expect a refund as a result of BudgetAir's incompetency.
