Frustrated, Irate at DSTV

I've reaching my breaking point with DSTV. I ordered a router last year, it took DSTV 3 months or maybe more to have the router actually delivered to me. Since I've received it, I've never been able to connect. After numerous calls, emails to them, still nothing. I requested to be called after 5pm in the week or at 2:30pm on Fridays. Instead, I get calls on Sunday mornings while I'm in church. so once again I call today, no history noted on my account. You'd think with an irate customer that's the first thing you'd do. However, nothing. she transfers me without telling the next agent why she's transferring me. Then I get through to SIYANDA at the internet division. BY now I'm upset as she has just transferred me without explaining to him why. I then request to speak to a manager because I'm frustrated, irate and tired of explaining myself. He refuses to comply and insists I speak to him. WHAT CUSTOMER SERVICE IS THIS???!!!! I have no decided to cancel my DSTV INTERNET AND SUBSCRIPTION. I'm just an ant to them and no one cares within the organisation but eventually your treatment of loyal customers will leave you'll with no customers!!
