There was a delay in their answering and the person had a foreign accent. I hung up so they rang straight back. When I answered they said in an angry voice “you hung up on me”
I hung up again after telling them where to go

Two missed calls from this number and no message left. I returned the call, the person answered with a foreign accent as being Telstra, I hung up. I highly doubt Telstra has individuals answering on direct dial lines as Telstra.

Caller: said they were from telstra

so i just hang up Telstra told me once before that they never call us for marketing or anything else so i just hang up they are very persistant if i want to deal with Telstra i will call them myself
