Bunch of ******

I received a call from someone saying that they wanted to help me with my financial situation. They asked me for the last number in my ID as a security check. They then went on about what they were going to do for me in a very obscure way. I asked her what this was all about and she rather abruptly ended the call. A while later I received an sms saying that I had given them consent to access my credit report, which I most certainly did not do. They appear to be a bunch of ****** and I wouldn't touch them with a barge pole.
