Bad Service by Standard Bank Knysna

We have a Business account with Standard Bank Knysna. Our account is linked to a Personal Banker namely Carlo Jonck. He is not customer orientated and therefore his service given to us is poor. We do not get feedback on our Queries and we need to keep on following up and then he does not respond to our follow ups. We sent through a query on 26 January 2022 and was promised that he will look into the matter and provide feedback.To date no feedback received and no acknowledgement on follow ups from our side What service is this,pathetic. Can someone please provide feedback.All requests is with Carlo Jonck of Standard Bank Knysna
