Refund still not paid

I received a call from Absa Two weeks ago that there is a refund due to me for being over charged on my interest and fees .They requested that i sent though my banking details and my ID copy as my card was closed and i have no account with them anymore . The amount was meant to be paid after 7 working days which was on the 21 July because they had a backlog .Yesterday i call ***to follow up as i was told to follow up if no payment is made in 7 working days.I spoke to a consultant who told me the refund was paid on Monday the 20th of July it should reflect in 48 hours which was on the 22nd of July .Today is the 23rd of July and the is still nothing and now this morning a different consultant is telling me the amount has been paid already,i should wait for another 3 days .So how does an EFT take 6 working days to reflect
