Dstv bad servise

Hi, I am really disappointed with dstv in January this year I upgraded to dstv explorer. With Hope's that I will be able to catch up my missed episodes as I'm always at work and the only time that I can catch up is during weekends when I'm off. I was told that the explorer comes with new installations meaning they have to change the dish outside and put on a new one. Well the dstv personnel came and did installation and told me that I have to wait for few days for signal to fully load all the catch up channels. I had always had one episode or one channel on catch up, with my lack of knowledge I was under the impression that maybe i have to pay dstv premium in order to enjoy the catch up benefits cause I am currently on compact plus. Until yesterday when my friend told me that she is also on compact and she is enjoying the catch up benefits fully, she advised me that I should contact dstv center. I spoke to Nonhlanhla and she told me that the reason I'm not receiving full episodes is because the signal is weak and that I need to call out the installation people to come and fix the signal, to my surprise I have to call the person and pay as if they are doing me a favour. Meaning all the extra R100 were just donations to dstv. I'm not happy very disappointed and I want dstv to fix the error without ne having to pay a cent and that return my monthly R100 that I have been paying for the past 3months
