Porting went wrong! HELP - I cannot lose this number!

[MobileUser]

Hello.

I am trying to switch to O2 from ID Mobile. I submitted my PAC on the O2 website but then it declined 3 times! When asking for a new PAC, ID Mobile says NO because the PAC has already been used! Does this mean I will lose my number?

I used to be really impressed by O2. NEVER AGAIN, IF I'M LOSING MY NUMBER! I need this number because SO MANY THINGS are attached to it! My bank account, my NHS services, even my home security! I need help please!

Thank you

Update - 

Unfortunately, in my opinion, this number is likely to be lost

A few days ago, 2 customer service agents told me that the port-in request would be cancelled. However, upon checking with the social media team, the port apparently will happen tomorrow. I am fully aware of British efficiency and it will likely mean that my number will be lost forever due to these issues

Is there someone I can complain to?

Official complaints appear to be taking around eight weeks and often customer services won't touch things while the complaint is open

I suggest you try Customer Service first; as @Enlli mentioned, by law, they have 8 weeks to sort a complaint. Any action a Customer Service will take will affect the complaint.
