Bad Service

I really do not understand why all of a sudden after i paid my installment well in advance, it becomes difficult for African Bank to update my payment records with Credit Bureau institutions, when calling them they said they will fix that within 7 days, i called after 7 days after checking my Credit Report with Transunion but still nothing, all this happened after paying the a large amount on 05/02/2015 now its a month and a half later still nothing. i am asking my self, Are these the results of bad Administration?
