Standard Bank RCP - credit score killer

I have been a loyal customer of Standard Bank before I could even afford a product from them. Today, Standard Bank is my financial reputation downfall. Being a business owner, cash flow and clients paying on time tends to be a headache. The rippling effects of that is missing a payment or 2 by no more than a month with payment arrangements made to avoid credit score damage. Not with the Standard Bank RCP. I have been paying my RCP account on time for at least 3 months and yet for the last 6 months or so I have been flagged on ITC as having not paid the account and that its in arrears. This is false account information that affects my credit score and ruins my financial reputation. I have gone as far as paying the minimum lump sum in order for me to access the revolving facility however I am apparently still under arrears and blocked out of the account. I have sent emails to query this and was told not to worry however to no fixing. I am truly disappointed in Standard Bank and will surely be switching soon. Frustration is only a portion of my emotion towards this matter. I kindly request that someone assist me in this regard because I am fed up now.
