Poor service *********** investigator

Since last month I reported a ***** case which was opened against my FNB account by a ABSA client everything was solved on the ABSA side even sent an email to an investigator named John Volmink but since till today no response sent him emails no response went to the branch they tried to contact him just unprofessional because when they closed my account no communication they just closed now they have to open I have to follow up the whole month from the 13th of May till 16th June service very disappointing honestly
