Self assessment Registration constantly rejected

I need to register for self assessment but every time I get an email saying the address does not match the records. I only have 2 addresses my Australian residence, my temporary uk address and now I am back at same Australian address How can I get past this to register.

Hi,
Contact us by webchat or phone via: Self Assessment: general enquiries - we can check the address we have for you on your record, and advise you further on registering.
Thank you.
