I have had this number and another extension call me 4 times this week, but I get nothing when I call it back.

same thing happened to me

It was me, sorry, genuinely called the wrong number

Don't know if this is a scam, but something weird is going on.

15-6-11 here we go again!!! I'm sick of these pricks ringing me.

Yeah i got this too. they call you answer and nothing call ends. you ring back and when it does ring it only rings for like 5 rings and drops out. im not to sure what this is!
