Broken arrangement I spend the whole day calling them and receiving different reasons from all agents I spoke to 10 alone today and still have no resolution to my query I am rather told we don't know why the agents said that but pay 3600 to settle no service no interest in my query just wanting me to do what they say robbing use from our money....
