Started billing me without permission or service provision, refuses to pay back money

<p>Openweb was my ADSL provider. I cancel my service on 13 November 2015 because of appauling customer service, which entailed never being able to speak with anybody with any technical knowledge, not returning calls and support systems being unavailable.</p> <p> </p> <p>From first July to first December openweb started debiting money from my bank account without my permission and without providing me with any services. I have approached them on 19th December 2016 and provided them with feedback about this problem and my banking details. They have said they would pay back the money and have not done so and are no longer replying to my emails.</p>
