How Can I Find Out Who Is Hacking Into My Alcatel Ot 880 Via Bluetooth

The data exchange icon comes on and as I unfortunately have ’nightmare neighbors’, I need to find out the IP address of the computer accessing my phone.The cursor moves uncontrollably downwards when I open web pages and eMails refuse to send occasionally in Google Mail when the data icon is showing.

Or can I switch off Bluetooth on my Alcatel OT-880 and access Internet?
