LLP UTR Not Issued

I incorporated an LLP in April and the UTR has still not been received at the registered office. The self assessment helpline are not helping reissue the UTR in the post and keep directing me to the corporation tax team, despite this being an LLP, not a Ltd company. Please assist in the best way to reissue the UTR in the post.

Hi
You would need to telephone 0300 200 3310 in order to give details for the reference to be searched for and a letter issued.
When phoning, ask for the taxes technican team.
Thankyou.
