bad service from African Bank

hi all , African bank service is bad , i opened a african bank account last year april , 2 months after that a loan with a zero balance appeared on my profile , i queried it at the branch , they sent me to the police station to write up an afidavit and state that i never in my history ever borrowered money from them african bank or its elifilites , documents uploaded took them 6 months to response via sms to say that (your request could not be met due to isuffient documents ) i called them immediatly and spoke to Sifiso ref no :*** he only response was that i re email my query again to them , and offered no help .. i asked him again if i had a loan agreement with them in 2009 that he keeps on saying send me proof where i signed or the agreement , which he cannot provide , thinking of switching my bank again to accomodate salary very dissapointed at them , service is terrible
