phone lost. cant get number blocked

I am currently in Thailand. MY PHONE was lost/****** an hour ago. Ive called the call centre twice and no one has been able to help me block my number because i dont have my vodacom account number on me. This isnt something that i generally carry with me. The agents wont offer any assistance whatsoever. This is pathetic service. If anyone from vodacom would like to assist you call my wife on *** or plse let us know what we can do by email [Email Removed]
