Can I please have a direct number or email contact for a sales enquiry for Perth, Western Australia?

Hi,

Is there a specific office or contact that handling Perth, Western Australia? If there is I would really appreciate if I can have their contact details, as apparently the Bentley Response Team can't call my mobile number nor can they receive my replies to their email answering their sales questions because I received the same questioning email 3 times so far.

Best regards,

Tuan Le
