worse service ever

i am so angry at African bank, i called in requesting settlement letters as i wanted to settle the accounts, the letters took me 7 phone calls for 3 days in order for me to recieve them , i called after making the payments i was told they not reflecting yet i sent through proof of payments to the team leader and the customer documents email, still the payments havent been allocated as yet when i call im told to hold for more than 30 minutes and still no paid up letters till today the settlement was done on the 28/08/2017 till today no paid up letter and no update sent to the credit bureau the airtime spent to call them can might as well pay an insallment on some other account im sick and tired of their incompetence they dont even know their facts one agent will say i see the payments the other will say no they not reflecting this is time consuming and its tiring everyday i need to call and follow up, when they wanted the money they would call now that its done no one bothers to update you
