Got a text from this number reading:

"Sir,av miss ur love and encouragement...I av been rejected by al.Kindly help my amalgamate D bond...

Then got a call from it a few days later, Indian/maybe African bloke mumbling and just saying "hello, hello". I hung up then he rang again a minute later. I've been using a spare phone and have been handing out CVs/applications using this number recently -  presumably someone has been selling CVs on to scammers/ID stealers.
