aehee lee Re-charged my account Internet

I ordered new service for Dish net cable, they were laied service package. However, I try to keep the service but it was more trouble and more charged my account. Therefore, I cancelled 2weeks after order. They had a policy 30days money gurantees. but they didn't give me a credit, so, I contact my credit company to dispute it get a credit back. After 2month later they charged 2month bills amounts is $106.28 again. When I received this bill I contact to them, they said will cleared my account but still send a bill every month.
