Incompetence and extremely poor customer service

My account was randomly blocked without any communication or information. I have on numerous occasions attempted to contact the team leader (Yolisa Doyisa), as I have been told that she is the only person in the whole of FNB who can uplift the hold or provide further information and assistance, to no avail. She also has not availed herself to get back to me regarding this query despite the numerous messages I have left her. I WOULD NEVER AND WILL NEVER RECOMMEND THIS BANK TO ANYONE, CUSTOMER SERVICE IS NON EXISTENT!
