Disappointed by African bank AGAIN!!

My experience with African bank...I don't even know where to begin. I've have been complaining about the same thing for the past three weeks. It's almost a month now since I've paid up my loan at African bank but their consultants keep on giving me empty promises when I asked for a paid up Lee three weeks ago. I was told by one of the consultants that it takes 3 DAYS to get that paid up letter, but to my surprise I found myself calling African Bank every week for the past 3 weeks asking for that paid up letter. Till this day I haven't received that letter. I hope this review will not fall on deaf ears. All I want a my paid up letter because I have paid off the loan how long must I wait 3 months maybe?
