Are the scam calls overseas numbers? Is there an option to block receiving calls from overseas numbers?
I searched everywhere but could only find an option to bar 10 NZ numbers on the Vodafone website. It's more than phone calls though, they could try to crack accounts using the number...
Vodafone blacklist will only stop SMS and MMS not incoming phone calls
They will not be able to crack accounts if they don't have the SIM card
