No idea. I never think I ever had a call from Britain that was legit. Pretty sure I don't have any business relationship with someone which name would not pop up on "phoneregister app" (this one lol). I just don't want to take them, alot of them just want a registered call to say "I tried to call alot of numbers! " So no idea what number is, just assume in best fall robo call, in worst someone that will make sure I make money by letting them invest... Sure, and take my car too!
