Status update

In the month of May I closed one of my accounts, received a paid up letter. On the 14th June 2023 I sent an email (***) to Experian SA requesting for them to update the account as closed. I sent an email because getting through to their customer care is a hassle where you need to wait 30minutes +- to speak to a consultant. To date it hasn't been updated, didn't even get an acknowledgment email nothing.
