No support from HiSense

I bought a HiSense TV through ebucks in November. From the beginning, the Netflix App is giving problems. I can log in and use it for a day. The next day, it will give a ui-113 error. I have to reset the app, log in again and I will be able to use the app for a day and so on. I went to the HiSense web site and sent a message via there support page. When I did not receive a response, I tweeted them. No response either. Next, I tried their online/chatbot on various occasions and times. I will always receive a message saying something like all agents are busy, leave your email and we will contact you. I was never contacted. Yesterday and today I went to the Netflix help page and tried the solutions offered. None solved the problem. Today, I chatted to a Netflix support agent who could not help either. This was not surprising, he used the same solutions that were on the website. So I phoned the 0860 number on the HiSense website. I selected 1 for service and was advised that I will be transferred to the next available agent. This did not happen, I went straight through to the rating voice prompt without speaking to an agent. The rating was accordingly.
