Can't believe there messages

I have wrote about them before not updating my credit history despite me paying on the agreed amount. They have contacted me regarding the last complaint but nothing was resolved. It is claimed that they can only update my credit report/history when the accounts in question are settled in full. This complaint is regarding wat they stating in there messages (SMS/email) is false. When the can't get hold of you, you reserve a message starting "avoiding our calls will have a negative impact on ur credit profile". Well despite having communication with them and paying the agreed amount as arranged with them my credit profile is negative. So people don't be fooled, negotiating with them will impact your credit profile negative. In the new year I will be taking up this battle as high as I can to report this company to the relevant parties despite having a arrangement with them and adhering to it.
