Incorrect listing of arrears and bad client service

Am utterly disappointed at this company that I need to again complain about you claiming that I have not paid for the month of April. I have a DebiCheck set up and it debits on the 25th of every month. I have never missed an installment but these is the second time listing arrears on my profile at compuscan. Am not having this, its affecting me negatively I can not obtain credit now anywhere else because you claim am in arrears. Called you contact centre they answer but ignore you and start a conversation amongst themselves which is totally rude. This needs to be sorted out immediately.
