Not happy at all

I bought a new cardless decorder today 13 July 2020. For the past 4-4:30 hours I have been trying to get a connection with no success. In between WhatsApp messages and 2 calls -still nothing. The error message was 1st E17-0, I called in and spoke to Sifiso, his service was great and I was connected before we ended the call, a few minutes later I tried to switch channels, I lost connection, the error was now E16-0. I rebooted the whole thing, gave it a few minutes and switched it on again but the message was/is still there, I did the whole WhatsApp chat again but found it to be useless as I was going around in circles chatting to myself. I called into the contact center again, after verifications the lady asked me to reboot again. I told her I was running out of airtime, can she just tell me wat needs to be done quickly -she said when it restarts I will be connected. The phone cut after that. I switched the decorder off and unplugged it, came back almost an hour later to switch it on -still no connection, its only channel 100 that's playing...I decided to try the live chat selfservice on selfservice.dstv.com. after verfications, the Bot advised that my query has been escalated to a consultant who would assist me -35 mins later, I am still awaiting. FYI, my account is not in arrears, I just want my decorder to be connected so that I can get value for my money
