Finchoice *****ing money from clients and inflacting fees!!!

I took out a 6months loan with finchoice which was supposed to end in February 2018. I saw a debit order in march did not dispute as I am aware of the one month arrears. In April a debit order of +-480 went off I tried calling your contact center to find out why I was debit I received no assistance was put on hold for a very long time while people were chatting in the back round.I then reversed the debit order and within hours received a call and spoke to a consultant and I told her I disputed this because I don’t know why I was being debited..i spoke to Thembisa Team leader whom I discussed with that I will account to my September instalment of R1484 and they can debit that furthermore I refused to pay for 436 for interests run in the account because I didn’t close it! No one told me I should close my account after it was fully paid I expected you to do that as we have a six months contract why keep it running longer when I am not receiving funds from you only just for you to make money out of me … I believe this institution does not do reckless lending nor does it charge customers unnecessary! So today I called again to get clarity of why R3039 was debit off my account in a space of a week R1484 +R1554I spoke to yisree (ext4198) who refused to give me his details who told me I was charged because I disputed debit orders and that his colleague didn’t give correct information(thembisa) I asked to speak to thembisa to understand why he **** to me and why he went back on his word and guess what? He said he is transferring me he didn’t he just put the phone on the side and I could hear him converse with his colleagues laughing at the back and he eventually released the line so what should I do now ??? I am being abused by finchoice I try to get hold of you to get clarity no one wants to help but you go in my account and take my money ! Should I take this to black twitter and the credit ombudsmen as well as the consumer protection act??? Your urgent response is requested !!
