Appaling lack of response on claim

I lodged a claim in September last year. I have been emailing the deathclaims email regularly for updates since 24 Jan 2019 and received NO response other than the automated reply saying that someone will be in touch "as soon as possible". You are requesting paperwork I do not have access to (and in reality do not need - as this has been confirmed by the people you have been in touch with) and you have repeatedly asked other people to fill in the forms with information I have already supp**** to the best knowledge of the people involved. Could you stop hiding behind red tape and process the claim please - or at the VERY least - respond to an email querying how the claim is progressing.
