Intersec int review: unable to terminate this subscription 1

MY CC was charged on 10/29 and 9/3 for $35.00 and $45.00 each time despite my attempts to contact this vendor and cancel my subscription; the phone number 917-671-0793 listed with the charges is not in service; I am not asking for a refund but want this service to stop and not to bill me again. There is no information motion on these web sites that allow you to contact the provider or cancel.
