Vodafone locked me out of my phone

I'm currently in Australia and wanted to use an Australian sim.<br> When I put the new sim in my phone, Vodafone Protect locked me out of my phone.<br> None of the links to receive a new pin work. Worst is, it attempts to send me a new password on my phone which is locked!<br> Very frustrating since I'm unable to use my phone's maps to get around in a city I don't know at all!!<br> I'm also only able to speak to a customer service representative between 8:00 and 12:00 because of the time zone difference
