@jamal This is not O2. This is a customer community. No one here can help you. There is this section from one of our guides:

If you are porting from another Network Mobile Operator to the O2 Network.

Porting your mobile telephone number to the O2 Network is straight forward. 

1. Ask for a PAC Code from your current Mobile Network Operator and then contact the O2 customer service contact us and they will take care of the rest.
2. Your current Mobile service provider will let you know whether you have fulfilled any contractual agreement you may have with them.
3. If you are bringing your own handset with you then ensure it is unlocked to accept all network sim cards.
   If your handset is locked to your current network then you will need to follow their process to request the unlocking process of your phone.
4. O2 will send you a text message on the day of the transfer to keep you up to date with things. 

Further detailed Instructions are here Keep your mobile number 

You need to speak to customer service. Best time to try to get through is 8-8.30 am.
