Pricelock will lock you

I was contacted by Dstv and offered pricelock in October 2020. They delivered the decoder in November but did not send an installer. They billed me for a full service in November and October, pricelock amount, but there was no installation. I stopped the debit order and tried contacting them to get a resolution. We are in May 2021 and I apparently have a balance on my account which is not allowing me to revert back to normal compact and I am sitting with a decoder that is not installed I spend over R500 on calls to miltichoice without a resolution. They are always escalating the matter. I went to an agent and the agent told me I must go to pricelock. I get to pricelock and they tell me all they do is offer new contracts they can't help me. I must drive to Randburg FROM PRETORIA. dstv pricelock service is disgusting and as it stands, I have no tv connection and no resolution. Sies!
