Still not allocating payments

RCS is the worst company ever!!!! My husband is having nothing but trouble with you guys. The following scenario happens every month. He paid his account (more than the amount due) on the 25th and for some or other reason they struggle to find his payment (reference they gave him) and then they charge him penalty fees for late payment which is never the case and they keep phoning him and threatening him with legal action. I want this sorted out. if you are not sorting this out I will contact the national credit regulator because as it seems to me that you are doing this deliberately to get more money from him in penalty charges and now it is also reflecting as bad payment on his credit record! you will be declared at the National Credit regulator if you don't fix your reports to the credit bereau and your system!!! I want to be contacted by someone in authority!!!!!
