Hi! So today I was called by a unknown O2 mobile number (07546) it begins with it is a 11 digit number. I tried calling it back but it comes up as invalid number.
Any help would be great!

Your best option is to block the number. It will probably be a scam call unless you have registered on a site that requires authentication? These sites just call to verify your number and calling back isn't possible.
