Missed the call but my phone flagged it up as potential fraud. Not sure what has updated on Android but that's the first time it's done that with a missed call
This number called me several times in one day so I answered it. The lady knew my first name and first line of my address. She said she was caling me from the payment protection team and wanted me to tell her which banks if banked with so she could send me the relevant forms. She also asked me to confirm my date of birth and post code for data protection. I didn't and ended the call. She was quite rude once I said I wasn't interested.
