UK, Ireland / How to renew Polish passport while in the UK? [4]

Hi,

So I'm British but married to a Polish woman who's been living in the UK (Brighton) for a few years. She wants to renew her Polish passport but says she's tried ringing and ringing the embassy but can never get through.

I don't really understand how it works but she's says she needs a code. She's currently not got a current passport as it's now expired.

Any ideas if she can do something different as she's going mad trying to wring the embassy day after day.
