Caller: Bad Scammers- my Truecaller App identified it

They leave a robo call message saying i have an order & need to pay $90 asap or they’ll deduct money from my account before I recieve my order & i need to call that number back. Im definitely not stupid, I’ve blocked that number.

Spam - message left. You missed a call from (08) 6146 2911, who said "$99.99 will be debited from your account. If you have not placed the order please call us 613." This message was provided by Telstra at no charge to you.

Caller: they said it was e bay

I rang this caller back on my landline and they said they were e bay I terminated the call but was doubtful as their number was displayed
