Unauthorised debit orders

Ticket [#***] I was contacted in Oct 2019 for a promotion on an Explora decoder. The amount I agreed on was R139 per month for a 2 year period. It was also advised that the amount of R139 will be debited from my account from end of Nov. 2 x Explora decoders were delivered to my home, which I didn't ask for. My agreement was for 1 only! End of Oct an amount of R139 was debited from my account for hotpspotter which I have also never authorised because I have Fibre uncap at home. End of Nov a further 2 amounts of R139 were debited for Explora. I queried it and was advised that according to the tape recorder I agreed to these amounts to be debited. I requested the tape recording to be sent to me, because I didn’t give authority for these amounts. I have in the meantime cancelled the debit orders for hotspotter and the additional R139. On Air agreed to refund the additional R139 x 4 (R556) for the second Explora to me which was done on 26 Mar. When I queried the hotspotter amount of R139 which was debited R139 x 5 (R695) I was advised by Kajal Pillay that I need to contact the call centre which I have done. I have asked for an email address for this particular department and was given the same email address. I didn’t authorise this amount for hotspotter to go off. I would like this refund of R695 to be done ASAP and honestly don’t have the time to start this whole process of communication again.
