No Debit Order loaded, impacts my ITC profile

About 4 months ago, I took out a loan with RCS, in April 2015 I received a call from the collections dept stating that I am in arrears and have to make payment, when I enquired with them as to why didnt take the funds they said I had insufficient funds in my account, which is not the case. I called them and made a EFT payment for April 2015. In May 2015 the same thing happened, where the Debit Order never ran, but on their side they say there was no funds. I am frustrated that RCS cannot sort out this issue, because it is impacting my ITC negatively. This whole experience is leaving a bad taste in my mouth. I want someone to sort out my Debit Order and ensure me via emailing me that I wont have issues June 2015.
