Poor bad service indeed

Worst experience I had with this soo called company nimble that I was not notified by Finchoice that their selling my accounts to them I paid even extra for the settlement that when I check under Finchoice it says I still owe R207.95 wherelse I paid R1603 in full it is supposed to say paid in full while they sent me the paid up letter but under Finchoice it says I still owe them..
