I demand a cancelation due to failure to provide services

This is my third complaint about DSTV Internet, it only worked for 3 days and reverts after loadshedding. I will not pay for services I am not receiving, they should take back their router and cancel my subscription with no extra charges.

This is more trouble than it's worth. The thing stopped working in the middle of my PC update and made a mess of everything, I am still trying to recover a lot of files and applications.
