No Last Name - Unable to confirm identity on HMRC [URGENT]

Hi team, I am trying to confirm my identity, but I don't have a last name on my passport or residence permit. Without my last name, the page is not allowing me to confirm my identity. I have also tried to enter my first name in my last name, as suggested in one of the HMRC forum's posts but the page throws an error: "The information you gave does not match our records." I have tried raising this issue in the support but unfortunately, the reply doesn't provide any solution. Please find their response "If you only hold one name or your name appears all on one line on your identity documents such as passport, you will not be able to proceed and create an online account. " Please give a solution for the above problem.

Hi

Unfortunately, if you do only hold one name, then you may not be able to register for an online account.
We should be able to advise you on alternative ways to do what you were looking to do with your online account, though - just contact us by webchat or phone, via
Income Tax: general enquiries

Thank you
