Caller: Claimed to be on behalf of Reserve Bank

Said they we conducting a short survey for the Reserve Bank about spending habits. Said a reward of $100 would be given for completing the short survey. Sounded dodgy . I declined and blocked the number

When you call back it picks up but makes dial tone. be wary

Has called a couple of times at odd hours. Treated as spam by my phone.

Phone said it was suspected spam, I didn't answer instead just blocked. No message was left
