No Refund received to date!!!

My dad booked return flights from Pietermaritzburg to Johannesburg for Dec 24th (Christmas Eve)2015. About 2 weeks before they were meant to fly, he received an email from Flygoair's IT Department saying that the all flights for that route had been had been suspended. With it being the festive season and wanting to spend time with family, they had to book tickets with another airline in the interim just to get to their destination. As a pensioner, that was a further unforeseen cost that he had to fork out of his own pocket.<br> <br> In the email it was requested that passengers supply their banking details for a full refund. He rep**** promptly with all of the relevant details including his proof of payment. We have both tried calling and emailing the airline numerous times since then and have not received any refund or further communication from Flyoair. The telephone numbers supp**** by the airline just gives an engaged tone. <br> <br> It has now been +2 months since the booking was made and still no communication from the airline. Please can someone assist with the refund!!!<br>
