Arrange Collection of Radio Link

On the 09 July 2018 I sent an email to cancel my services with ADT, confirmation of cancellation was received on the 12 July 2018, after I had given the reason of moving from my property. When discussing the collection of the Radio from the premises I was told they would need to speak to the new owners of the property to inquire if they would like to continue with the service. Surely with the POPI act this is not correct. I have not been able to arrange collection of the radio because of this and I am moving out in two days, I refuse to take responsibility for this radio as I have tried to arrange this with no success
