Reqest UTR number

I failed to apply UTR nuber online as HRMC emailed me that my address incorrect information. I called to HRMC and reconfirmed that my address is recorded in system without any mistake. Under this situtation, HRMC staff advised me to fill in SA1 form, print out, sign and then post . I have been posted the form to HRMC more than 2 months ago in April . Regret that until today, there is no reponse or letter from HRMC to me. Please advise what I can do ?
