Worst experience United US 125 Euro II 2021

I had bought new United 125 from Akbar market karachi around Feb 2021. But I am having such a bad experience that I just want get rid of the bike and buy any 70cc bike that the extend to which i have got irritated with the bike. And I have done some research on my own and found out that this fault wasnt in my bike but the same exact issue was with all unitied 125 bike bought recently. And no one is figuring out how to resolve this issue. I went to many mechanics one say's and other says something else and not been able to catch the fault. There is a kat kat sound whenever I change gear and after 5 to 6 days chain gets loose. I am so frustated that I feel have invested Rs. 85,000 in garbage...
