BAD SRVICE(BILLING ISSUE)

I am very disappointed about the service that I have been receiving from dstv.Every 7 days my services gets disconnected and I pay on time . The problem started when I re- activated xtraview and I have since sent an email to for my billing to be sorted till day no one has responded to my email. I have sent another email again today requesting for my billing to be sorted. What's worse is that when you call the call centre the consultants are very rude and dont want to assist.It is very annoying that ONE HAS TO CALL DSTV WHEN YOU ARE DOING THINGS RIGHT. I AM VERY DISSAPONTED BY MULTICHOICE AND THEIR SERVICE!!!!!!!
