Call-Direct Dont want to provide information

Last year I took took a personal loan of R30 000 with Call-Direct and I have been a great customer to them as I have never defaulted on repayment of this loan. On the 13th December 2014 I made the payment of R12 000.00 to *** and that Call Direct account number. <br> <br> I asked three Call Centre Agents to tell me when will my loan repayment end. All three of them they said it will end in 2017/04/20, as per original agreement. That doesnt make sense to me, because that should actually reduce repayment term. I have an extensive experience in the loan industry and I can atest that every time the client makes an advance payment of their loans it actually reduces repayment term. I dont understand why my loan have to end in 2017 wheres I have already reduced my loan repayment by almost 50% of capital amount borrowed. <br> <br> This is a totally reap off and they are taking people for a serious ride of which is unacceptable.
