Terrible service

Had a simple problem that needed to be fixed. First of all they were hours late. Supposedly the problem was fixed. Got home,tried to change channels on Dstv and everything went dead. NO signal!! This was a completely new problem that didn't exist until these so called technicians fixed the original problem. Phoned Arthur himself and was told that I needed a new decoder. I honestly think the cables were tampered with because when I took a look at them and tightened connections it started working. Just because I'm a woman don't for one moment think I'm useless. After paying a huge callout fee they then want to make more money out of me. But hey maybe they should hire me as clearly the technitions don't know what they are doing..or do they ( we will come back and charge you more ) they will never set foot in my house again.
