Caller: Scammers

I don't think the actual owner of this number is to blame but I do believe it's being used by scammers claiming 'someone has made a $xxx transaction on your credit card and we will assist you to undo it'. When I said I would check my credit card transactions on my computer and get back to them, they told me not to and kept saying that I shouldn't do anything except what they were going to tell me to do. I told them I thought it's a scam and wanted to check elsewhere first and hung up. The phone rang again from a different number 0403 679 558 and it was 'the supervisor' pressing me to follow their instructions to fix my problem. I asked them what my name and what credit card number had been compromised and they couldn't tell me. I called them some nasty names and hung up but then my phone wouldn't work for about half an hour.
