Hi.
Sorry to read that you are having problems. But please note that this site is not an official Microsoft site and is not affiliated to nor endorsed by Microsoft, so any complaint about the phone will not reach Microsoft.
Also, when posting please provide a meaningful title to your topic so it can be useful to others while searching and browsing. Also, please provide any useful information about your phone brand and model, and you didn't mention the problems you are having, either. Note that the system is buggy, yes. But your problems might have a solution or a workaround. If you know the Windows 10 version you are using, that would be helpful too.
If your phone did not come with Windows 10 pr-installed (i.e. it came with Windows 8.1 and you chose to update), you could go back to Windows 8.1 using the Recovery Tool.
Not all is lost. There is still some hope.
