Complaint against DSTV/Multichoice

I took Cntract with MultiChoice , DSTV and Internet, in October 2023 I noticed that the Router does not connect it has a red ligh. I phoned them serveral times trying to resolve this issue but never get assistance till I decided to tell them to Cancel the Contract but still they are billing me and the bill is accummulating. I do not understand why the still billing and I do not even pay the DSTV because I am paying for data that I am not using. My name is Xolani Msadu Contact Number ***
