Dstv(multichoice )problem

I have paid my monthly subscription for January and I have error E16.I have two weeks and my decoder only display channel 100.I tried to clear the error on WhatsApp and failed. I contacted multichoice on 23th jan they failed to clear the error also from their side and they confirmed i dont owe anything.They advised me to take it to their service center and I dont have insurance,so have to pay double now.Help me get refund for this month cause I paid for nothing.JACOB PHAGO-ID NO:***-CONT NO-***
