Bad business

This company I canceled my subscription few weeks after I recieved their moderm. They didn't have coverage in the area I live but sold me the package knowing that there is network coverage. The modern never worked since I recieved it in April and after a week I canceled my subscription. Now they are always trying to debit my account every month even when I canceled in may. It was a month to month and I paid them for 2 months. They took their moderm but still trying to debit my account no matter what. I called more than 3 times in 3 months regarding this but they still debit no matter what, their service is very poor and always apologizing for trying to debit but after a week it goes again. This company is really a bad adverti*****t and their people just sign you up even thou know theres no coverage just to make sales.
