Disgusted DSTV customer

I have been trying to contact the creditors department from Thursday 12/09/2019. I have spoken to numerous call centre agents and 2 team leaders, all promising to get the creditors to contact me, but till now on the 17/09/2019 I have had no contact at all. DSTV has listed my hubby stating he owes them R480 000. like really will DSTV give us service if we owe them R100 let alone the above amount. The call centre agents all tell me we do not owe any money, only our installment due for the end of this month. All we need is for them to give us a letter stating we do not owe them any money and to contact the bureau to sort this out, we are begging them to their own job which I think is highly unacceptable. I am utterly disappointed and disgusted with the service we have been receiving. This is not the first time DSTV has been unprofessional in assisting us.
