Not receiving the assistance I need

I called Capfin before end of Nov to make an arrangement of payment because I am currently unemployed. The consultant made an arrangemnt for me to pay R450 and R50 in Dec to cover my monthly installment for R500.84. The last day for me to pay the R450 was 7/12/15 I was not able to pay the installment on the day but on the 08/12/15, I called Capfin to ask if I could pay my installment in store, because my bank account was in arrears, the consultant said yes and gave me an in store ref. I then went to my nearerst Pep store and paid the R450. The next day on the 09/12/15 a debit went off my account of another R450 the same amount I paid in store the previous day, I then complained, I was told that I wont be able to get a refund, and that the system was set to debit on the day, I spent the rest of the week last week moving from consultant to consultant but no way forward. Right now I am unemployed, I was retrenched in Sep, my account is up to date. I need Capfin to make an arrangement with me to debit R102.00 end of Dec, becuase right now you guys have my R399.00, I am frustrated and I need someone who will be helpful to me to assist me and not another merry go around.
