No device received from Neotel / Liquid Telecom

In February this year I received a sales call from Neotel, wanting to sell me the Kwezi device for my television for R999. I agreed to this, and agreed to pay the money requested, whereupon the device would be delivered to me. On 27 February 2018, I paid the money into the Neotel account and sent the proof of payment as requested to email address they had mailed me the order from -----> ********** This email bounced back. After a week. I still had not received my device. After 2 weeks, i called the customer services. They promised to look into it and get back to me. I left my number. They never got back to me. I tried a second time. The did not get back to me again. I tried a third time. This time, when I called, I was put through to FIVE different people before somebody could help me. The guy who helped me, gave me his email address -----> ********** to send him the proof of payment. And so he could follow up. His email bounced back. Is Neotel in the habit of giving out false emails as a pretence for helping customers? I have now still not received word from them or even assistance. I need my money back or the device I paid for ASAP.

Thanks
