register self-assessment rejected

After applying to the self-assessment, I was rejected for the following reason: We are unable to process your application because the address provided does not match our records. But this is my current address and I can confirm this address is already updated in Personal Tax Account. I check it online and the solution I got is to contact Self Assessment department directly to register. Can you give me the contact number? Thanks

Could you please provide a number so I can call? thanks very much.

Hi,
You will need to contact us by Webchat using 'ask HMRC Online' and asking to speak with an adviser.
This will put you in the queue for Webchat:
