Bombarded me with calls 3 times in a row. No msg left!

Saying from Telstra Billing, had some of my details already, but i ended the call as it didnt sound legitimate

Calling from Telstra offering 50% off for the next 6 months of bills don’t need any details from my end then hung up on me

Caller: 0455 944 066

Called saying they're offering 50 percent of further Telstra bills. Knew my name? I hung up immediately. They kept calling back so I had to block this number otherwise they wouldn't stop calling back.

Today I was bombarded with calls from this number and when I didn't answer another number would come up . Finally when I answered the call it was supposedly someone from Telstra giving me 50% off my mobile bill. When asked questions I didn't feel comfortable answering, I hung up and they continued calling. I called the number back nobody was answered. I too received a message on my mobile to reset my microsoft account password. Guys just be aware!!!!

called multiple times in a row and wont speak or leave a message

Claimed to be from Telstra billing department and offered free points. Then they sent a multi factor authentication text message to reset my microsoft account password.
