Must Customers Beg when they want to settle their Accounts!!!

On Tuesday 5 June I contacted EDCON Contact Centre on ********** 000 wanting to settle my JET STORES Account after learning that I still owe them. They advised me that they cannot pick up my records on their systems after I provided them with my ID Number and the JET Account Number. A lady called Renay Hendriks said that she will try and found out if the account has been handed over and who is responsible for it. On Wednesday I also e-mailed ********** for assistance. On Thursday I received e-mails from Mzamani Ndove & Busisiwe Ngqolowa advising me that the matter was handed over to NIMBLE GROUP/Norman Bisset. I then contacted this Group/s to get more details including their banking details and reference numbers to make the payment. I made about 5 calls and none of the Agents at NIMBLE GROUP/Norman Bisset could trace my records as they advised me that I do not exist on their systems and referred me back to EDCON who also referred me back to NIMBLE GROUP/Norman Bisset all over again. I have just sent an e-mail to Busisiwe, Mzamani, Renay at EDCON as well as info@edcon e-mail address. None of the reciepients have responded to my e-mail not to even acknowledge although Outlook has sent me confirmation that my e-mails were received and read. I have also copied ********** info@edcon, ********** and still no response. Is it how it works at Edcon that clients must be sent from pillar to post and beg when they want to settle the accounts??? Is this how EDCON treat it's customers??? Why cant they(edcon) take back this account and allow me to settle it with them. I need answers as I've been trying to settle this account from Tuesday 05/06/2018 and it is today Friday. A lot of my time has been wasted here and I cannot afford to wait any longer to settle this account!!! JET STORES ACCOUNT NUMBER: ********** ********** 13078
