Bad customer service

If there was a zero rating I would give South African Airways a zero. I called in 16 October to cancel a flight ticket and I was told to send an email. I sent an email 16 October, until today the 23rd of October I have note received a response. Flight date is now near and SAA is not attending to my cancellation request. It is so sad that they do not take customers seriously and want to rip them off.
