Lack of good service

I am a DSTV Compact subscriber ( Customer # ***0, ***, Card number ***3). <br> In December 2014 I had an issue with the connection between my decoder and the outside dish and eventually had to pay R500 to get the issue resolved by one of the installers. <br> Today I'm experiencing error code E30-4 , this error occurs every time I attempt to change channels. <br> I have followed all instructions to try and resolve the error but still cannot. This means that I will be paying a subscription for channels that I am not enjoying. <br> <br> Thank you for the excellent service you have been proving thus far however I feel that you NEED to FOCUS MORE ON YOUR AFTER SALES CAMPAIGNS as there is still a lot of work to be done. Your error handling process has never worked for me as I still continue experiencing the same issues. <br>
