Nonsense customer service

I sent an email with account closure forms on the 23rd February 2022 for my linked investment account and still haven't received any feedback/balance in that account. This is the 3rd time I request for this account to be closed so I don't know if it's incompetence/just intentional poor customer service. I even went to the branch several times but still no one seems to be doing their job. It's total nonsense that a customer has to request a simple thing for over a year. I don't have time to keep following up just to get feedback so I'm just annoyed at the service I'm getting from Stanlib
