Caller: Male with accent stated that he was from Telstra Technical Dept

I said I was busy and would call back in 10 minutes. The number he provided showed no results so I can only assume it’s a scammer! I won’t be calling back. I’m so annoyed as I have been home this week on sick leave and have received 1 to 2 calls every day including the weekend, from Telstra scammers on various phone numbers. I didn’t realise they were that persistent! I asked one of them if he was a scammer and he said you are a scammer, enjoy your time in jail. I wish there was legislation to prevent this scourge on innocent people!
