Hello this is Carol from Telstra
Like f*ck it is

Left a message about cryptocurrency credit card charge of $500 and to press 1 or 2. Message finished with very loud banging sound.
SCAM

SCAM- Called to say that there was a charge of $900 AUD for a gift card purchased via PayPal and to press 2 to speak to an operator regarding the unauthorised transaction details. Suggest to hang up and block the caller

Telling me my Visa card had not been debited because it was treated as a suspicious transaction - never purchased crypto before.

I don't have a Visa card and wouldn't touch crypto in any event.

This is cyber security we’re going to delete your phone account. Fark off

Caller: Scammer

Automated voice from ‘Visa / Mastercard’ admin claiming a charge made on my card.

Received a call from this number. No recorded message. Assuming yet another scam/telesales call.
