Unhappy client

On the 03 March 2025 I've suspended my service with dstv they asked for the serial number of the decoder cause I have two decoders and they disconnected the service with emmideate , last week I was checking balance of how much I was suppose to pay I was not certain about the balance I then make a breakdown of the balance and I saw I was suppose to pay two insurance for two decoders. I've sent them an email for the clarification about the balance and why I was paying for insurance of the decoder that has been suspended in time I was to contact insurance department regarding the matter, I've ask why I was been told when I was requesting explanation about the account. I'm not the with the way dstv has handle the situation I feel like I'm paying insurance for a dead person.
