Utter incompetence

This company doesn't even deserve the 1 star that I'm giving if i could leave it blank i would. Angry doesn't begin to describe how I'm feeling right now. I had a 6 months flexi loan with finchoice which according to the settlement quote, payment made and paid up letter i received, was paid in full and closed with a 0.00 balance. 3 months later After taking out a funeral cover I get an sms saying Congratulations your finchoice Africa loan has been approved we will send you an sms when your money has been deposited. I logged on to their website because I didn't apply for a new loan and to my surprise it shows the 6 month Flexi saying i am in arrears with R301. I called them to find out what was going on and they told me that my account is in arrears i ask how but i made a payment and i got a paid up letter. They said they see the paid up letter but they dont see the proof of payment which makes no sence. To avoid any unnecessary drama i sent the settlement quote letter the proof of payment and the settlement letter and i forwarded an email from them confirming i was not in arrears. This morning i get a call asking me why my account is in arrears with R602. I lost it asked the consultant that is my question to you, how does an account go from Paid-up to in arrears by R301 and now you're telling me its in arrears by R600. The consultant gave me an attitude saying there is no need to be angry in just trying to help. How are trying to help when you are messing things up. I need this sorted out by finchoice and they must cancel the funeral policy because I can't trust anything they say.
