Debit orders not cancelled

<p>On 1 February 2017 I requested that my two contracts with Yellodata be cancelled. I received confirmation of cancellation on the same day.</p> <p> </p> <p>However, the debit orders still went off at the end of February and March 2017. I informed Yellodata of this on 28 March 2017. They requested proof on 30 March 2017 , which I sent to them on the same day. I received no further feedback and reminded them again on 1 June 2017.</p> <p> </p> <p>Still no feedback and still the debit orders go through each month.</p>
