British Airways and Discovery ****ty service

I booked a ticket from East London to Joburg for the 5th of September, via British Airways. No ticket was received yet the money went off my account for a ticket that didn't exist. Upon follow up to query this, I was RUDELY told that there is no ticket for the flight that I've already purchased. I then went through a series of back and forth calls and emails to prove that the money had gone off, only to be later directed to Vitality by BA for them to process the refund. It has been two weeks since the last email was sent and still no reply. I've tried to call them on countless occasions, the most recent of which left me waiting for 26 minutes on hold only for the call to be disconnected on their side. I'm yet to receive my refund, after a month of waiting and having paid for a new booking because I needed to get back to Joburg. PLEASE CAN I HAVE MY MONEY BACK!
