As other comments. Says from Telstra. She called 3 times. Could be ? Indian" accent

Claims to be from telstra and offering discounts on mobile phone plan

Caller: Telstra

Indian female said she was from Telstra, then when I questioned her she handed me over to her supervisor who was also Indian and she proceeded to say I'd get 40% off my telstra mobile because I was a loyal customer and had been with them for ages, she then read out my details and the email address she listed for me is not linked to my Telstra account, so this confirmed my suspicions that it was a scam call.

Called three times and did not leave a message.

Same as stated above
