No service

No Service at all . Since receiving my decoder i have sent 2 What's apps phoned 2 times and there was no consultant available and asked to leave a message but then the line goes dead , I also emailed customer service and got no reply. So I have a decoder that i can't do anything with but they sent me 2 what's apps to make sure there was enough money in my account for the Debit order to go off. I want to return this decoder but do not know how. I also don't know what package i have as i was not told , but i was promised that i could watch all the Super Sport channels. The consultant at Multi Choice could not assist because i was not told what package i was signing up for. We also tried to phone the help line and was greeted by an AI voice who was useless ! So what do we do now ?
