Bad service/bad attitude and double billed

My husband and I has had the most horrific experience by using your airline. Firstly we booked our tickets online and what do we get a double booking made on our credit card whilst on holiday we had to block our card so much for the inconvenience... Money randomly taken off our bank account which we were unaware of which was highly unappreciated!!! To top it off we still haven't been refunded quick to take money from us and than it takes forever for the money to get refunded to us!!! Pathetic service from the call centre as well there is never an answer when trying to resolve an issue , we waste our airtime , time money and effort how frustrating try putting yourself in our position !!trying to get hold of someone to assist and to think nobody reimburses! Secondly on our flight back to Johannesburg from Cape Town international airport my husbands luggage disappears we landed at Or Tambo airport exhausted as I'm an expecting had to wait for hours to find the luggage no assistance at all from the baggage controller like what the hell??? We left the airport without the bag!!! His exact words to us I need to go home it's late and my time is up as arrogant as ever
