Scammer claiming to be Amazon and will be debiting cards for money

Got one call, didn't leave a voice mail.

Male voice said hello. I asked which scam he was running and he hung up.

called, no message left.

Caller: Telstra

Says from Telstra, that someone is using our number over last couple of days. I worked for Telstra, they just say 'head office', well there is noone like this there. I said his mother would be ashamed of him. He got a bit upset and said, well she knows what I do? Getting so so tired of this, why don't the telcos read these posts and block in their systems. They are internet generated numbers apparently too. Surely something can be done?

Called and didn’t leave a message. Suspected scam.

No message. Don’t trust it.

Can’t call back. Def a scam call.
