Tantamount to theft

I registered for my N1 in February and was advised I could write exams in November. I had a death in the family in March and all of the sudden Oxbridge changes the dates to August. I called in to say I cannot meet that deadline, was advised that I should cancel and would get a 50% refund. Now after I submitted the cancelation I'm advise I wont get a refund. I paid R14700 upfront, cannot believe how ************ this organization can be and they linked to Advtech the only reason i decided to go with them. I will be logging a further complaint with the Ombudsman and will take this up further. This is blatant theft, you cannot change dates as you please and tell your customer its your own problem, not acceptable.
