Customer Service

I bought a 74" 4K Smart TV a few months ago. The Disney Plus app does not work properly on it, stalls, blanks out, and sometimes the menu bar disappears. The app works perfectly on my smart phone and laptop on the same Wi-Fi connection. Trying to get hold of the support at Skyworth is proving to be a nightmare, no response to my on-line requests, every number on the website rings and then cuts off. Regretting buying this brand, should have stuck to the more popular brands. Customer service is non existent.
