What happens after depositing money in Luno?

Could you please elaborate on the process that occurs after a user deposits money into their Luno account? What specific steps does Luno take to ensure the funds are safely credited to the user's balance, and what sort of notifications or confirmations can users expect to receive to verify the successful deposit? Additionally, how long does the entire process typically take, and are there any potential delays or factors that could impact the timeliness of the deposit being reflected in the user's account?
