Caller: Martin from Federal Govt Solar Rebate

Indian or similar accent asking questions about my electricity bill

Who keeps calling me, no one there

been called by this number, don't know who this is

Called twice and silent

Caller: Blocked number

Calls daily, and 'missed call' displays, despite being blocked weeks ago when smart phone flagged the caller as 'suspected spam'. Attempts to return the call and request being taken off the call list unsuccessful.

Did not leave a message. When I called back it went through to voice message saying "this number could not be reached, goodbye." and cut off. Presume not a legitimate number.

Phone call but no message was left

No message left - scammer?
