Capitec bad treatment of client

Money was deposited on my account on the 13th September 2023 and they put a hold saying they suspect ***** and I should ask the sender to go speak with their bank and they did on the 15th September 2023.

I was then told it will clear after 48 hrs and until today the money is with capitec, they are making interest for themselves and they are refusing to uplift the hold or send back the money to the sender.

I always heard about this bank bad treatment of its clients and now I'm experiencing it. They don't respect their clients. I have called many times with no solution.
