Cash Call is great for getting you money really quick...but they charge such high interest rates, it's scary! I took out a loan from them more than a year ago, and I've been paying them $199.02 a month since then and have only paid down about $50 in interest...you do the math! Of course, you can always pay additional money to them every month and pay less in interest, but I have unfortunately not been in the position to do so.
I had to default this month for a couple of reasons, and they've been pretty nice to deal with, but by and large, if you can avoid them, I would.
Hope that kinda answers your question.
