Worst service I've ever had: from ordering; to billing; to support!

1. I ordered DSTV Compact on Price Lock online but I didn't have some of the documents they needed with me. I went back to the site when I got home, but I couldn't complete the order, so I went to the branch to have the order completed there, and they made me start from all over. The lady told me that even if I had successfully placed the order online, I still would have had to go open an account instore (sounded strange to me);

2. They promised to call within 48 hours, but I didn't hear from them for close to a month. Every time I called, they would tell me "the issue has been escalated" and promise to call within 48 hours, and nothing.

3. When they finally delivered the decoder, they delivered two decoders and billed me just over R1700. I called the call centre, they promised to send someone to pick up the decoder and that didn't happen until I went to hand deliver it to the store in Centurion.

4. At the store, they "escalated" the issue, and called me later that day confirming that the issue was resolved and that I will not be double-billed again. But that didn't happen;

5. A week later, my service got disconnected. I called the call centre, and they told me it's because I didn't pay (and I had). Upon further investigation, it turns out they disconnected the wrong decoder (instead of the one I took back to the store). So they reconnected it again;

6. A day later, another debit order went off taking another R1700! Again! I called again, and the agent told me I was billed for two decoders again! And she promised to "escalate" the issue again. I asked for the phone number of the department she's escalating the issue to (because cleary they seem to be the people who are better positioned to assist), and I was told that department does not have a phone number, it's off limits!!!!!

I don't know what's more annoying, having to go reverse they debit orders and having the issue being "escalated" all the time! In addition, I still receive sales calls from their agents asking me if I'm still interested in ordering (something I already have)!!!
