Just received sim, new number?

[#1]

Hi,

I've recently transferred from O2 and during the sign-up for the deal I entered my PAC number to transfer my number but for some reason I've received a new one?

Why did this happen and can this still please be corrected? I don't want to use a new number

Thanks
