I bought a TCL 32S327 32-Inch 1080p ROKU Smart LED TV (2018 Model). the first words in the product description were easy voice control . The remote control in the package is not one with voice control. WHY To get a voice control I must buy one at $20. it should come with the tv.
I'm not sure where you bought it, but the first 3 places that came up when I searched say you can add voice controls by using with an Alexa or a Google Assistant. Most retailers will take things back if you aren’t happy – even more so if they described it wrong!
