I had a missed call on my mobile number and land line number this morning which I found out was the dwp. They have just rung back and it turned out she was returning my call!!!! I told her the last time I rang dwp was in October. She then asked was my name alveras, but couldn't hear the surname due to loss of hearing. I then told her I am a woman called Caroline. It turns out she was dialling a land-line number to my mobile number. Do you think I have been hacked?
