JD Group Misrepresenting customer's account

I bought Couches on credit on June 2017 at Rochester. I was delivered first week of July 2017. I was told by Rochester that credit will be handled by Joshua Doore JD. The first installment was supposed to be invoiced on 28 July 2017, and it was never invoiced. I call Joshoa Doore in this number +27 (0) 10 ********** and got call center people who answered. I explain my story that they did not invoice my account. However those people did not know how to help me or who to transfer the call to. They told me that when they check on their system the mistake is on Joshua Doore because there were supposed to invoice my account end of July 2017 but they did not. They keep on transferring my call until the last person dropped it. I called again, still they could not help me. I made the other call on December 2017 still no one could help me.

On 28 April 2018 this year, first installment was taken from my account after 9 months of delivery. Then I received an SMS saying my account is in arrears. I then received a call from people in Port Elizabeth branch JD group. They told me about arrears in my account - meaning they picked up this after 9 months. I told them my story that you are the one who never invoice my account you can not save me as a bad payer that will make my profile as a bad payer. The person told me that she will escalate this problem because I was not supposed to be added as a bad payers since it them who never invoiced my account. On May I got the other call again saying my account is in arrears I should go an pay my account. I tried to explain the same story, then that person still said the same that she will escalate it because this account was not supposed to be added interest if it them who did not invoice it. I then told the lady that even if I want to pay I do not have Joshua Doore account number because the agreement was that they will debit account every 28 of the months until I finished paying. June and July still received the same call and explained the same story. The person said the same as others, I will scaleless this problem. It looks like all these people who called me are not winning with the escalation and every month they keep on calling me and tell me this.

My problem is, Joshua Doore JD is dragging my name as a bad payer. I never missed my payment but they they did not invoice my account for 9 months then when they picked about I am now labelled as a bad payer without investigating what happened. There are also interest added. this is really disappointing me that if the person was supposed to invoice and never invoice why this affect me for their employees competence. This is really decreasing my score and is unacceptable.
