Green coffee Fulfillment Center Pure Green Coffee Company can not be reached for explanation of charges to my account and cancelling order Canogo Park California

I purchased a bottle of Pure Green Coffee Plus in response to an on line ad.  I received bottle with a letter stating that I would be receiving another bottle within a month and that if I was not interested I could contact customer service number listed.  I received another bottle within a month with no accounting or charges listed.  I contacted customer service.  She said that she couldn't help because their computers were down but to call again.  On subsequent calls since Oct 7, there is a recording that the phone number is no longer in service.  I do not have a website to contact and would like to cancel further shipments immediately.
