Hi there, 
 
Thanks for reaching out to us, and I'm sorry to hear about the situation. I want to check if you are still in need of any help. If so, a few questions: Are you located in North America or Europe? And what type of Nest Thermostat do you have? If you have the Nest Learning Thermostat or the Nest Thermostat E follow these steps: 
 
 - Press the thermostat ring to bring up the Quick View menu.
- Select Settings.
- Turn the ring and select Eco.
- Turn off both the Eco Temperature.  
- Select Done.  
- Turn the ring and select Nest Sense.  
- Select Auto Schedule.  
- Select Off.  
- Select Done.  
- Turn the ring and select Home/Away Assist.
- Select Done.
- Turn the ring and select Reset. 
- Select Auto Schedule.  
- Select confirm Reset. 
- Turn the ring to reset schedule.
 
For Nest Thermostat 2020, try these: 
 
 - Clear weekly schedule.
  
   - On the home screen, touch and hold your device's tile.
- Tap Settings > Schedules > Clear weekly schedule.
 
- Adjust temperature preset on the thermostat.
  
   - Back to Settings > Temperature Preferences > Temperature Preset.  
 
- Restart the thermostat.
  
   - Go to Settings > Restart > Restart > Yes. 
 
 
Let us know how it goes.
 
Best,
Zoe
