Poor admin performance by Edgars

I have paid my account on 30 November 2018, I pd R600 which was more than I needed to pay. On 7 December I was contacted by Edcon collection who requested that I pay my account immedaitely. I informed them that I did pay and have the receipt prove as well as my bank account to verify this. I was told to visit my store to find out why my payment is not showing on their systems. At the Edgars store in Oudtshoorn, I was told that their server burnt and that the payments could not be updated. I agian contacted Edcon customer service and they refused to assist me and again said I must visit the store in Oudtshoorn, here I was met by the manageress of the store who informed me that Edcon H/O sent her the prove (receipt) that they requested I sent them and said that I everything was sorted. On 10 December I received another call from Edcon H/O informing me that I did not pay and that it was as such updated with ITC. Edcon refuse to take responsibility and has now influenced my credit record. I was advised by my lawyer to lodge a ******** charge with the SAPS as this constitutes *****. Edcon still refuses to assist and said I must again go back to the store in Oudtshoorn, I cannot keep on doing that. My proffessional body as an accountant , does not take bad credit records very lightly and I could be suspended and will not be able to do my work as a result of Edgars' actions.
