Pawn Mart Paid interest for months and still sold goods without a call Snellville, Georgia

I pawned an iPad and a ring. I told the manager I had to get the iPad back. I paid every month. When I went in a week late in December to pay on the loan, they had sold the iPad and refined my ring because they claimed I was 60 days late. I was visibly in shock, and no one offered to print out my history on the loans. The man working said, "Come back tomorrow. We open at 9." I walked out in tears. I had to go out of town the next day. I spoke with the manager the next day, and he said he would call me the following Monday. He called, and explained I missed a payment.
He defended the company's policies, and said, "our computer does not make mistakes." The company's policies are unethical, and they do not care about nurturing individual accounts or repeat business.
I think this store should be closed for unfair business practice and fraud.
No one ever called me to tell me I was in danger of losing my goods, I believed I was up to date. Oh and I called the main corporate number while I was away, and no one ever called me back.
This company does not care about the person who pawns, you are their bread and butter.
They essentially "steal" from those coming in to pawn, I paid more in loan extensions than what I borrowed,  and then they sell your merchandise to those coming in to shop.
I would never do business with this company again, and I have a large network of friends and associates, and I have spread the news about their poor customer relations and willingness to prey on those in a difficult financial situation.
Very shady company with poor business ethics.
