Just tried to telephone Google Sydney office to speak to the accounts department. My associate has sent four email since 6/10/17 with a request for an invoice. Reception kindly responds but to date no response from accounts. Unfortunately there is no accounts telephone number, just a reception number that goes nowhere other than advising me to send an email. Cant give a zero rate and post, so one star to be able to post. Google Accounts obviously does not like the little people. This is very poor!
