Dishonest, ********** & unfair customer treatment

I booked a flight online through Egypt Airlines and SAA Airways (code share flight) (SA/YGMM3W reference and *** flight number 7Aug2014SA260 JNB to Frankfurt & 11AugSA261Return). Several days beforehand I became ill and decided to try change the flight or get a credit to use at a later date. Egypt Air rep**** and confirmed a refund. I confirmed this with the local RSA office (Elizabeth in Accounts) and through various emails too. I also verbally received confirmation from the RSA office that Egypt Air would honor their email, confirming the refund, when I phoned again before the flight double checking this fact. After chasing up my refund with the international office by email several weeks later, I was told that the previous person \had made a mistake"and I would not be receiving a refund as the flight is not refundable. This 'flight conditions' fact I knew as I had initially requested a credit note to use later on a later date/flight"
