Horrific Service - NO Service

I was hounded by Finchoice daily for months because I had a sudden decrease in my commission for a few months. I made payment arrangements which I have honoured and 6 days ago was able to settle my account of R7964. I sent through my proof of payment numerous times. It's been 6 days since I made payment and it still reflects that my account has not been settled. I have been liaising with Hayley from Finchoice and all she keeps telling me is that she has emailed the necessary department. Still, no one has bothered getting back to me after 96 business hours. I want this to be addressed immediately or I will take legal action. Worst ongoing horrific service over the past 6 months I have ever experienced in my life!!!
