I received a missed call no message was left... When I returned call, went straight to voicemail (strange the male voice just advice to leave a message) did not announce who he was or which company he was from, just advise to leave message, I quickly hung up, believe to be a scam...

Caller: Something to do with an ISP device

Asked if I'd received an ISP device, I think for a Solar Inverter - couldn't really understand. I said I'd received it (I haven't) and it works a treat. She didn't know what to say to that and said 'ok thank you' and hung up.
Seems like a new type of scam.

Caller: 8804 5812

You always know if there's silence when you answer then someone with a very strong accent speaks, it's a scam. Something to do with a hot water attachment, the caller couldn't explain. Second call today and have received several over the past weeks. If no one answers straight away, it's a scam and I hang up.

Two calls yesterday and three today from this same number. I answered the last call, got the robocall delay followed by call centre noises so I hung up. They're persistent if nothing else.

Must be a scam
