Refund voucher

I sent a cancellation request on the 11th of March to cancel a ticket due to a deceased family member. I sent the required document as proof. I received confirmation to say it will be cancelled and a voucher will be sent it has been four days I an fighting a battle of getting a voucher sent to the email which the already have on their system. I have wasted money calling and being put on hold only for my calls to be be dropped I find this very *********** and misleading. I am meant to leaving for Cape rltown tomorrow morning I cannot book because I have no voucher nor pin number which is suppose to be provided by them. In calling several time none of the assistantsame showed in remorse having expressedhow upset I was of their incompetence. This was going to be my first experience with this airline I will not recommended it to anybody nor will I ever use it again. I want my voucher and some sort of reimbur*****t for all the trouble that i had to go through trying to fix what is not exactly my job to keep calling for my voucher.
