Refund not paid after 4 months of complaining

On the 29 October 2015 I cancelled my flight that was sheddulled for the 31 October 2015 due bad service provided by two staff members of Kulula [URL Removed] Call Centre.I spoke to Ryan Gregory abt me travelling after I had a injection taken in my back.I was fine to travel and had my Doctors note.He advised me that he will not allow it as he thought i was unfit to travel.I asked him how he could make that decision without seeing.I then requested to speak to his Team Leader.He then told me that Shana Liebenburg will phone and find out from the department who makes that decision if I will be allowed to Travel that day.Shana came to the fone and I explained again my story to fly earlier and explained all of the above.She first told me she will try and arrange something but after i complained to her that her request of asking my doctor to give another letter at 4pm was ridiculous as he was in theatre at City Hospital She immediately denied me travelling.I asked to be put through the department who makes that decision for me to travel.She put me on hold and said Sorry U cant travel.I asked to speak to her Line Manager, she said there was no Manager.I then complained via email to Moyra Poultney.
