Poor service from Fnb home loan

In January 2021 I asked my private banker to assist with a home loan cession, he requested I send him my life cover documents, which I did. I have been sending him emails to ask for an update on the request since the initial request in January 2021, to my surprise he doesn't respond to my emails anymore, The last email I sent was last week, I have probably sent 4 or more emails asking for feedback, I still haven't received any communication from him. I don't think a home loan cession should take this long to action, I'm very disappointed at the service I'm getting, and honestly I am even considering moving to another bank. I'm at a point where I have decided not to tolerate this bad service I'm getting.
