SA airlink refund ****

I booked a return flight from Cape town to George in the month of January. It was my birthday and a friend was visiting me for my birthday. Due to the bad weather on Sunday 12 Jan the flight was not able to land in George. Safety first I agree. Flight return to Cape town and I cancelled the return flight, since my friend never arrived for my birthday celebrations. Same day I sent an e-mail as stated on the website to apply for refund. Next morning I phoned airlink. Two days later I went to see them at George airport.. I send another e-mail 3 days later. The phone call and personal visit I was just informed " they are working on it". I have not received any reply on the e-mails now 2 weeks later. Surely it is just good business etiquette to reply to e-mails even if they tell you. "Sorry sir, we can't help or you dont qualify for a refund". The person on the phone or airport could just say: " It is not my portfolio, but let me connect you to the person that can help you". So now more that 2 weeks later, I guess I will never get a refund, but SA airlink really need to improve their communication and reply to e-mails in 3 working days as stated on their website.
