Hisense 65” tv malfunctioning

Good day, I trust you are well. I have had my 65” uhd tv give me led problems. It was repaired last week and delivered to me yesterday. I now find that it does not connect to any internet connection. I have set the tv so forth. It doesn’t allow you to manually addd etc. It just says no result. I am honestly so disappointed that this is the second issue this month I am having currently with this tv. This tv is not even two years old and this is the problem I am faced with. Honestly I am so dissatisfied with this tv because evidently it going to continue to give me endless problems. I would like for a manager to call me and see what can be done from here on. Either replace my tv or cash back because I will be taking this to mass media if this continues or this is not responded to timeously.
