OK this just happened to me today and is freaking me out. I will share this with you chaps to see if anybody has had a similar experience, or some possible explanations of the situation.
I recently put a new sim card in my PAYG mobile as I have moved city and could do without some people contacting me (female fans ).
Today I get a phone call from the collections dept of my bank telling me I am a few pounds overdrawn and must pay it back etc etc. We are only talking #20 pounds here so it is not serious. I tell them piss off and hang up, as you do.
HOWEVER, just after this call I realized that I have just changed my sim card and almost nobody knows it, let alone my bank ?!?!
The only official bodies I gave my new mobile number to were my local doctor, a hospital, and a couple of jobs that I had applied for.
What the hell is going on ? how did they get that number ?
Conspiracy theories are not normally my thing but this has got me thinking
