No Response to Emails

Despite send numerous emails to Absa I get no response from Private Bank or from my so called Private Banker. All I am trying to get to the bottom of is why my account is being credited with odd amounts like "Acb Credit Settlement R66.54 Bal Hfood ***". The credit appears on 11 November in my cheque account. Who is sending this and what is it for. If I get no response then it may be my lucky day. It is not a problem that Absa Stellenbosch is not attending to but it is a Private Bank problem and my so called Private Banker who also ignores my emails
