bad service. paid up letter has not been sent or any feedback regarding account closure

Hi my reference is ***8 for the edgars account paid. I have settled my account as per settlement quote given in the 27 October 2019. I have not received any feedbacks from the company they ignore my emails and calls. The account was paid on the 31st of October in boulders FNB branch and reflected on the nimble group account on the 1st November . One of their consultant called me on the 1st of November I confirmed that the account was paid yesterday the consultant said its not yet reflecting but I should keep the slip which is what I did however at the end of the call the consultant sent me another settlement to paid till 30 November which I did not understand as I had confirmed the account is paid and the settlement now was for 5000 and more the manger of the consultant that made the arrangement where he could have sent for account closure is Elijah Mkhonto. I really disappointed and frastrated at such bad service and unprofessional the consultants are. I wish I could have paid the account at Edgars stores because this is really unprofessional. Now they are not responding to any of my emails. Please help me get my paid up letter and clear my name. The proof of payment is sent ans the screenshot of the sms I received for the settlement quotation
