Headaches with DSTv just continues

I was very excited to get my new Explora Ultra with a 24-month contract in February from DSTv. After installation, it took us 4-weeks to get everything working as it should after a great deal of run around on our part. Apparently, the new decoder has a glitch causing the Extra-view to cut out. Eventually, the installer advised us what to do if this happen. We had a week of viewing, and the next morning the brand-new decoder was dead when we woke up. I went through all the hoops again and took it to Waterkloof Glen DSTV Centre for them to tell me it was not working and they have to swap it for a new decoder. BUT HEY DID NOT HAVE STOCK. They will phone me. It is now three weeks later, and I'm still awaiting a call from them! I phoned them just now, and the agent put the phone down in my ear when I insisted on a timeline for when we can expect the replacement decoder. GREAT CLIENT SERVICE DSTV! We have taken Showmax, Netflix, and Disney Channel because of the decoder's ability to view these channels. I'm paying all this money, and I can not enjoy any of it! DSTv was quick to debit my account with my monthly fee at the end of the month - but not quick to assist with my problem. Please HELP me!!! It is a never-ending battle with them!
