Pep help desk refuse to reprint.

My father went to Pep cell Mokopane 4629, their contact is ***.He purchased Flash R500, vodacom airtime R12 and R5. He came back home, he realized that he misplaced the slip, he went back to Pep and explained to them, they still remember him, they checked their transactions and they found that he was telling the truth, they contacted pep help desk, pep help desk didn't allow with the reprint, my father just lost R517 today, because they refuse to reprint from the help desk, my father is over 70 years, he is depressed because he used his Saasa money to by those items. I am not happy at all, my father is not well, we buy everytime at that store, they always give us good service, the problem is their help desk, they refuse to assist us.
