I am sick and tired of overseas scam callers no using mobile numbers to get through the Telstra Call Guardian phone system. I no longer answer mobile numbers I do not know and that are not registered in my phone book. I have now blocked this number too. I have listed this as a scam caller because the last call of this type that I answered was from a call centre claiming to be from the Government Solar Rebate Scheme of which there is no such scheme that would be calling randomly.
