Period of Administration Income

I contacted HMRC 7 months ago with accounts for my late aunt's Period of Administration - until these are agreed and I pay over the Incoe tax due, I can't finally settle the Estate and 12 beneficiaries are waiting. Two letters and three calls later I have heard nothing. I made a formal complaint in mid-August and have received no contact except for an automated response (say ing I would be kept "fully informed" of the progress of my complaint). I spoke to an adviser yesterday who confirmed my letters and the complaint had been received and said that someone would call me back the same day, or the next day - no one has. Please advise the next step I should take to escalate the complaint (and include complaining about your Complaints team).

Hi
We are sorry to hear about your experience and regret any inconvenience caused. If you would like to file a complaint you can do so here:

Thanks - but as I stated in my original post - I had already made a complaint over 6 weeks ago and have still heard nothing. I have now made a second complaint using the same method (your link, which simply directs me to the page I used before). I was, however, asking how to escalate a complaint when your dedicated Complaints team ALSO does not engage with me. It seems a little pointless to simply keep making complaints via the same method, if that results in nothing being done, except an automated response.
