Spotloan TOTAL RIP OFF Palatine Internet

 I need help I borrowed $800 in January of 2016 from Spotloan. They take money out twice monthly $127.11 and it is August 2016. Somehow I signed over the Internet but I am a senior citizen on a fixed income and have paid them over two thousand dollars back and I still owe them $800. I called my bank to see if they could put a stop payment on these people and they said no that they use a different name each time they take money from my account. I would have to pay $31.00 every two weeks to stop them and they could ruin my credit. I need help I can't keep letting Spotloan destroy me. If I would not have paid them three times over but they never stop going into my account. So apparently I signed something online I didn't understand. Cheryl H
