We cancelled ours last year. I dug the original connection sheet out and made sure I paid up to the date of connection. Meaning we took it out on the 29th July and I paid up to the 29th of the month I was cancelling. I then phoned head office in Instanbul and said I was going back to UK in 2 days and wanted my Digiturk disconnected. We were not on any tied in contract. The cheeky sods tried to persuade me to just have a break as I may want to come back to Turkey. When I said no they said did I want to sell it to a friend??? Stuck firm and said I wanted it cut off. Half hour later no Digiturk, following day went to local office with remote, scart, and box and was given a receipt. I have had no problems since. This is my experience but I know lots of people who have had problems and end up somehow owing money to them.
