Scam?

[Pip01]

I've received a number of anonymous calls, don't recognise their numbers. A contact of mine tried to phone me but my phone didn't ring although I watched the 'missed call ' counter increas rapidly. When I phoned them they said my line was constantly engaged. Today, someone I don't know phoned me saying they were returning my call. I hadn't phoned them. Could someone have duplicated my number? I suspect my data allowance is going down too quickly. Any suggestions welcome.

It could be that someone is spoofing your number so if this is the case there isn't anything you can do to stop them but if it continues and if you have had this number for 12 months or more then speak to Sky about them cancelling this one and issuing you with a new sim that will have a different number attached to it and while you can say it will never happen again you would be pretty unlucky if it was to happen with this different number.
