Refund not done

So I went to this flight center at mall of Africa in November to book a flight for December with rwandair. After the president announcements regarding traveling ban, I went back to cancel my flight. So the traveling agent mphumi told me all is fine they will refund the money. But up till today I'm chasing them for the refund. She is telling me it will take 3-6 months. This is ****, I want my money😭😭😭😭 She said she spoke to management and flight department they confirm that my money will be available within 3-6 months, what kind of service is that??
