It is great to have proof from your side but even then you might have
a hard time getting the ISP to accept it.
I had a similar problem with MTNL TriBand with their Nights UL plan
(circa 2005).   I got billed for Rs. 9K and I was bloody sure I had
not downloaded that kind data during the daytime hours.   At that time
I did not know about vnstat and other such tools.   I am convinced
they were using a buggy method to record the usage.

Without going into the SNMP solution, you can try out Untangle CE
proxy server in the "GW" box that Vivek has suggested.  I believe the
CE will give you summary of individual station data downloads.

The fact that you don't know anybody in the neighborhood does not mean
they will not use your connection :)

Security - it all depends on the Wi-Fi security option you have chosen
- min. WPA2 Personal with a "strong" passphrase.   In my neighborhood
I see quite a few APs with WEP and one is completely open!

I always turn OFF the WiFi on the edge device and use another AP plus
restrict connections to "known" MAC addresses.
