Finchoice loans

I was offered an R8000 loan from Finchoice, of which they only gave me R800 to start with. I called them to ask why only R800? They told me they take R200 as the admin fee. They deduct their money from my account every month. After 2 months later I was in between jobs and I called to tell them that I do not have money at this time as I am between jobs, that they must cancel the debit orders and I will start to pay R200 per month towards my account. They said no problem debit order instruction will be sent through to accounts department. The following month they debited my account for R1500 and I had it reversed. Thereafter I got a notice saying I owe them R3800. I have been paying R250, R300, R800 instalments but they continue to harrass me after recklessy loaning me money on a R5000 salary. I would like to make arrangements to pay R50 a month until I can afford more as I am the only breadwinner. I feel like I have been cheated as I was not given the money which they say I am owing. Finchoice is a terrible company which cons poor people out of they hard earned salary. I am very annoyed and feel abused by Finchoice.
