Unable to identify ID when setting up HMRC account

Hi, I have tried to set up a Personal tax account/HMRC account using an international passport and I am unable to do so as the system stated there is a mismatch of information. I have spoken with the HMRC helpline and they have checked that all my passport details are what they have on the system. Please kindly advise me regarding this matter as I have no other forms of ID that I could potentially use as I do not have UK driving license/provisional driving license Many thanks
