Competition Prize still pending

In March I won a Valentines day competition. You had to send in your voice note explaining who you loved and why you loved them and you could win R1000 and a Sorbet voucher.. To this day I haven't received anything from 702. I'm really disappointed that they did this after I explained that my partner and I were unemployed so we really needed the money. I don't think you do that to people. I think it's just selfish and very inconsiderate of whoever was running the competition.
