Bad Service

I have been using dstv for more than 10 years and always paying my account on time every month. Suddenly two months ago I started expiriencing problems with my account and disconnecting my account for no reason. Now I owe R164 that I don't know where it comes from because I always pay my account on time. Dstv service is bad... I must phone a call centre every 5 days to reconnect my dstv.
