PAYE and Self Assessment queries address - BX9 1AS

Hi, I spoke to a web chat agent in May earlier this year to raise a query about my self-assessment. I was advised to write a letter to the PAYE and Self Assessment department, at the address: HM Revenue and Customs BX9 1AS I did this 4 months ago but received no response. I'm writing a follow up letter, before I send it can someone please advise if this is the still the correct address? My issue is regarding the marriage allowance. Thanks

Can an admin please confirm this address, thanks.
