I will take the responsibility for the experience that I have had with this company due to not checking/understanding their interest rate/s on their line of credit. I therefore would like to make the public aware of the pitfall. I have been paying more than my monthly payment required by the company. I have only checked my statement properly this month, and I was totally shocked. I was charged R224-90 interest for 1 month on a balance of R1173-32. I trust that the public will be wary of the credit pitfalls by this review.
