Finchoice "Double Charging Accounts"

I took out a 6-month loan, long-term loan and a funeral policy with Finchoice. I paid regularly. I lost my job a year ago, but I kept paying my accounts because I still had my husband's income. My debit orders are scheduled for 1st of every month. Sometimes my husband's salary arrives on 27th, then i go on Finchoice website and pay my accounts via EFT. I also sent my proof of payments to their Accounts Dept. I paid the full last installment of my 6-month loan, yet end of August, I had another total on my 6-month loan? End of July I noticed on their website statement, that even if I pay via EFT, they still add R1100 onto my account, for unsuccessful debit order on the 1st, yet my accounts were paid via EFT. First week of August I queried my accounts and asked for a printout of my loan accounts, so that I can see how many times I was double charged, because my balance does not come down. I still have not received any printout from Finchoice. I am in the process of having Finchoice investigated. Finchoice add amounts to our accounts, which is not right. FINCHOICE SHOULD BE INVESTIGATED. ***
