Cash Advance USA review: So-called cash advance usa loan

I've been getting letters and collection notices for at least a few years from legal teams supposedly representing you. I've never used your service. I'm tired of being harassed. I'm a 70 year old widow living on Soc. Sec. I've had open heart surgery and a shoulder replacement recently. I had to move in w/ my daughter and son-in-law a few years ago. I don't borrow from anyone, because can't afford payments. Please stop all your legal teams from harassing me.
