Spot Lo@n review: My debt increased and it was mistake, but the company hasn't fixed it

I took the credit from Spot [protected]@n. I needed to pay $230 monthly. However, due to financial problems I missed two payments. I called them and explained the situation. The rep n friendly voice told me that it was ok. He advised me to wire them two payments of $500 and I would be able to pay again this $230. I have done as the rep told me, but when I checked my account it turned out that my debt increased. The rep assured me that it was only error. But they still haven’t fixed it.
