They've changed their tune. This time it's the NBN calling 'on your landline because of a problem with your internet'. I didn't bother telling him that our 'landline' is actually a VOIP line. However, I did suggest that he go forth and multiply, or words to that effect.

so i just got a scam call from CBA (This Mobile number). Apparently Someone transferred $900 to someone in USA. I requested they give me the bank account number. He couldnt tell me. So i said, "whats the name on the account". He said "Jogi". I then asked " How many people do you scam a day"? He said " Including you, around 50. I make Millions". I said, well you didnt scam me. Im to smart for you". He turned around and said " You f*cking Australians. dumb sh*t f*cks and hung up.

Caller: Some guy claiming to be from mastercard

Beware. It's a scam. Person will claim you have transferred a lot of money and that they're from mastercard trying to help you. Don't give any details!

Is this a nuisance call
