Need to phone passport office

[AaronLo_1875925]

When I try to phone the passport office on 09135 950999 I get a message saying, "Sorry, you have not been given access to that service."

I have £10 credit on the account and a package with unlimited calls.

I've checked alternative number websites but there is no alternative number for the passport office.

The passport office doesn't let you turn up and ask questions without an appointment. The only way to contact them is by phone or mail, but I don't have time for mail. How can I phone this number?

Edit: I have also tried 0844 556 9340, but get the message, "Sorry, your call cannot be connected." This number also doesn't have an alternative number.

@AaronLo_1875925  Using gov.uk website (therefore not a scam rubbish site) please see: https://www.gov.uk/government/organisations/hm-passport-office. They give a totally different contact number based on 0300, which should be fine to call.
