What can interfere with cell phone signals

I feel great sympathy for your sufferings. However, have you ever tried to communicate with your neighbors? If the communication is invalid, you can try to call the police. Of course, if you don't want to cause too much excitement, there's a product called the cell phone jammer that works for you. It can quickly disturb the surrounding mobile phone signal and keep the phone silent. Of course, please be careful not to interfere with those who need to use the phone normally.
