DStv (MultiChoice) Price locked Nonsense

In October 2019 I received a call from your sales consultants who offerd me your explora on a price lock package which I was happy to replace the decoder I had for the explora. The explora was delivered and I had to go to the nearest Office(Durban CBD) to activate it however when it was time to pay in November 2019 I was charged twice for the old decoder and the explora and again in December 2019 I was charged double when I called your callcentre I was told I was suppose to call you and cancel the old decoder but how would I know that if your consultants don’t tell me. You called me and offerd me the explora if there was something I needed to do on my side you should have told me this when I was offerd the package.

I have been paying for a decoder that I no longer use because of your *********** consultants and it not fair to me to be charged for something I no longer use. I would like to be refunded the amount I was charged for the old device as it not my fault that a new profile was created instead of changing the old profile to the explora.
