Relating to various services listed and is a phishing/scam number. Number can't be called back either from Telstra mobile network.

They hung up when i answered. Tried calling the number back, but there's no ringtone even - will be blocking them. Thanks for the above comments

Told me he was from Amazon

Caller: (03) 9123 1052 identified him from Telstra

My husband told me that he answer the call the guy identified himself from
Telstra, saying to call this # (03) 9123 1052 to fix his phone issues with spams, then my husband told him that he will go to Telstra Shop tomorrow, he then say that if he go to Telstra they will charge him $200 and he can do it for free but he needs to call the above number, clearly SPAM

Tried to tell me I had subscribed to Amazon Prime and they would help me unsubscribe by going to their website. Yeah right!!
