Home loans department has no TAT takes months to respond to clients emails or request even fnb complaints doesn't really help much

I have sent an email since 19th May however no response from home loans as per below email sent to hlpricing and wealthpleasehelpme, and even on complaints has been received. The only response I got was only about the rate review, what about the other questions even so I sent the email on the 19th of May but it always takes more 10days for a response at this point no response at all since then Good day Phenyo,

Thank you for your response, therefore, I am requesting for further rate review because I mean there's no difference at all, like happened.

Again, I have received an email regarding details of my home loan account, as per the attached. The debit order amount stated is different from what's being debited monthly. The difference is R126. 64, please check that.

I would like to find out the process to change the co-owners to one person. To be specific, I would like myself to be removed as one of the co-owners.

As per this email above sent on the 19th, it's the 2nd and still there's no response. I'm really disappointed
