Last week I recieved a call from an number i didn't recognise I phoned the number back and an old lady answered the phone I said I'm returning your call she said i haven't called anyone i said you did you called me she said no it's wasn't me she then hung up. Today I recieved a call from another unknown number (came up as a mobile number and norlt the same number as last week) again i didn't answer but I did call back and again an old lady answered the phone. I said I'm just returning your call again she said i didn't call you i have only just got in. I hung up but I recognised that the voice was the same old ladys voice that called me last week. She didn't ask me any questions or want anything so I can't think why she keeps calling. Does this sound like a scam? Anyone else had this?
