capfin

I have an issue with capfin. I have taken 3 loans with them. The first being in April of last year of which I paid 6 installments. They offered me another loan at the end of September of which I paid 3 installments. In December they offered me a bigger loan which in double of what I have taken thus far while settling the previous loan like they did previously. I have to date paid 7 installments uninterrupted. As of the end of May having paid 5 installments already, I enquired If can take the same amount again. I was told there is no funds available. last month I did they same and got the same response as I did this month. Now unless my math s****s has decreased I calculate that if they give me a loan of the same amount as December minus the current remaining balance of R12419.10 there is a total of R14580.90 left which would help me as I need it urgently, but I keep on getting told there is no funds available. Or maybe my calculator is less advanced than Capfin's. This is unacceptable and bull****. I really only needed one of the loans I took. The others I took because I thought it would help my credit rating. So I will on giving you negative rating until you help me when I really need it.....
