Someone with an Indian ? accent said he was from Telstra No call register (I am not a telstra customer). He verified my address and wanted to know if my Visa card still had a valid date of 2021. Then he wanted to know if the front number started with 4, I guess he would then have got me to quote the whole number. I then told him I was "pulling his leg" as I knew he was a scammer and hung up. They then rang back on a Private number and tried again, but we just hung up on them.
