"Tesco Mobile" scam emails going round (UK)

[Rich-Allen1976]

Above.

I've been getting messages from "Tesco Mobile" all week on my main Gmail account asking for details, several years ago I did have a TM account, but this was before I was with GiffGaff and then O2.

I have blocked/marked the messages as spam but they still come.

Is there anything I can do? Tesco themselves won't do anything.

I am aware of Google.
