Can someone port my Sky mobile number to another provider without Sky notifying me?

[GillMuscat]

Can my number be ported from Sky without my agreement?

I have had a series of SMS from Vodafone this morning 

 - saying an email account hes been added to my (very old, unused) vodafone account

 - that they've updated my account

- that I've made an order
 - that they are getting ready to move my (current Sky mobile number) over to vodafone on 8th Sept

 - that my SIM card order has arrived (in Woking!)

I contacted vodafone; they said contact Sky

I am working out of the UK at the moment and my attempts to contact Sky keep being cut off as the automatic system doesn't register my inputs. 

Any idea what I should do as I'm sorry worry my number will port and the scammers can then go on to take over other accounts.

Thanks

You are going to have to find a way to contact Sky support about this so if you can't call them try Facebook Messenger or Twitter.
