This is the correct procedure for any abuse case, should you want to take it further...
You need to open a Police case for bandwidth theft or possible fraud. Once the case number has been issued, you need to request the Investigating Police Officer to get a Sec 205 subpoena made out in the name against Telkom SA Ltd. On the Sec 205 you may request the following
- The telephone numbers used to access the ADSL platform with the username: "USERNAME@ISP";
- The registered owner details of the identified telephone numbers; and
- the physical installation addresses of the identified telephone numbers.
Once the Sec 205 has been issued, the Police Officer needs to hand the Sec 205 to their Technical Support Unit for delivery upon Telkom SA Ltd.
