Gagasi 99.5 fm winner winner— NO DINNER

I won the grand quiz on Gagasi FMs Uprising with Felix and Minnie, 4 consecutive days (3/12 to 6/12)… But seemingly I just won on air because no one then asked for my banking details- which I still provided after multiple calls to the station. The year is 2025, I will haven’t received my cash prize despite this being announced live on radio. Please assist!!
