Please immediately contact your current service provider. JB Hi-Fi Mobile is brought to you in partnership with Telstra, however there is no need to contact JB Hi-Fi Mobile or Telstra, as we cannot cancel it for you. The number is in transit and is therefore not in JB Hi-Fi or Telstra systems yet.
If you suspect your service has been fraudulently transferred (including if you suspect that it has been transferred without your permission), you should immediately contact your current provider, and the Australian Federal Police or the relevant State or Territory Police immediately to report that activity. You should also immediately report that activity to Scamwatch or IDCARE.
