Scary receive call and noone answers

Appears to be a scam. An Indian accepted young female says "Customer Service calling" but she is unable to name the company or organisation she is providing customer service for.

I call d back the number 0420 845 669 and reached vm that did not mention the company name

Also had a missed call from this number... after reading the comments on here I have also blocked them. No VM left.

Rings once then hangs up. Obviously some sort of scam.

Just received a call from this number. Obviously someone is behind the call as I could hear some weak background noise, however no conversation. When called back, just hung up on me. What？

Keep getting calls from this number. They don't leave a message. Number now blocked.

Australian voice, she was saying something about changing to solar power... I hung up

Australian voice. When I asked who the company is she just hung up on me - how rude! Number is now blocked.

Caller: Unknown

Don’t answer, Just BLOCK THE NUMBER!

Receive call, no one answers, call back line is busy

Has called me twice, I let it ring out as I don't know the caller, theres no voice mail left thinking it my be Telemarketing

Received a call, answered and no one answered.

Same thing - answer phone and nobody speaks!

Missed their call and they left no msg. When I called back it said service currently unavailable. Added number to my block list.
