What exactly do you mean by "My phone number has been compromised" and "shufted to other phones or is travelling across cities and fraudulent sites"?
What exactly has happened to your number?
What "other phones", cities and fraudulent sites are you referring to?
What exactly do you mean by "identity theft" here?
Your phone number can't be ported from 48 to another network without the porting security text being sent to your phone and it being entered into the relevant mobile phones service provider's porting request form.
If you need to contact 48 support about this then see the links in my signature below.
