Called 3 times & never left a voicemail or responded to my text.

Scam caller impersonating Telstra. Calls from a variety of similar mobile numbers with only the last 2 numbers changing

Called twice in a row, never left message. Probably a spam call

seems its a scam call when call back computer recorded message saying it is customer service team

Scammer, probably phishing scam.

someone call me without any sound,fk

Called but made no sound and said nothing

Hangs up immediately. Beware of scam call.

I called back and the voice message said it's from the Customer Service Team. No company name provided. So must be from a team that only cared about "customer service".
