Insure paying me with a voucher instead of cash

My TV fell, firstly my Discovery app did not work, I contacted Discovery insure and the lady insisted I have to log it online, I explained that it was my first time claiming, long story short I called back and only then I was assisted, the lady did not sound very cheerful to assist. She first told me my claim was approved for an amount that I could not even find online for my size tv, after I emailed her the link and a screenshot she updated the quote amount. I am unhappy because Discovery Insure sent me a voucher code for Makro, I want the choice to buy my tv from wherever I choose from. Why not pay the cash in my account I asked, I did not quite get a valid explanation, just that Discovery deal with Makro and Takealot and I don't know who else. I do not pay my installment with a voucher, it is cash from my account, so why do I get paid in a voucher?
