I keep getting calls with regards to a person called Sima to my mobile number this has been happening on and off last 12 months mostly tell them they have the wrong person and that I have held the number for over 20 yrs and no one by that name has used this number. they hang up and I block the number and then they call by another number sometimes landlines and other times mobile numbers. they try to say I have won prizes in comps, amazon prime is the latest one and that was this number it was an Indian speaking person or it is an automated voice either way in the end I end the call or they hang up and I block but I am over it all!
