Cancelation fee paid and no reimbur*****t

Onair is a ****, paid the cancelation fee in March with in a day of having the their decoder after been given falls marketing by the telesales person, was told that they want to update my dstv decoder cause it's old and I'll be paying only R200 and something for the new one and not explaining that for the channels I'll be paying a separate amount only got that information when I called Multichoice customer care that I'm not the only person I've been given false hope too. Till today no collection of the decoder and they have the audacity to send me the sms about reinstate my debit order when I let them debit on the account for 3 months after paying for the cancelation fee and I was told those payments will be refunded to me and that's when I canceled the debit order on my side.. May they just please take back their decoder back before I sell it to reimburse myself.
