apparently, a wrong number, calling from a call centre in Sydney but I couldn't find the number listed

Caller: Scam

Every day this week I have received a call from different variations of this number. I block it, and they call from a different variation. Scam telemarketer from overseas call centre offering rebates on solar panels. Every day I tell them to stop calling and they don't stop.

Whe answered I was disconnected.

A pesky call centre I suspect.

Accidentally answered and met by crackling line. Hung up and blocked number
