Credit Bureau not updated

There was a misunderstanding regarding the payment of the installment for Cell C However the amount was paid up in 2014 and CELL C has not updated this on the credit bureau as yet and we are now in 2017. Trying to contact the legal department for 3 days now and there is no answer and no one can assist me at the customer service contact center, we have app**** for a bond and it was declined because of this. I have called about 3 times now to request them to update this and it has not yet been updated!!!! Cell C service is honestly pathetic, once my contract is ended I will never use them again. This is affecting our lives negatively and no one seems to care at Cell C. Even their staff is ***********. I am beyond annoyed and is now considering legal action.
