Weird phone call help?

[Lara]

5 minutes ago i got a really strange phone call and my mum answered it said 'is lara there' and my mum anked who is was and an robot sounding voice with an american accent said she was live on station 7 (anyone ever heard of it)? and then i went on the phone and it said someone was giving me a shout out, and they asked me to take a guess who it was and i said beth cos she's my bestfriend and then after a pause she went 'nooo, it's shaun' and then they said they had to go and I don't know anyone called shaun so is it a fake or what? x
