Complaint Death claim

Death claim!! My husband passed away in Sept 2023 .The attorneys did inform them UT the lorry stopped there.I thought the lawyers followed it up and they thought I did.In October 2023 I send an email to pensions and got a automated reply that rgey will report back to you within 3 to 5 working days...That never happened so I did ask again and again. On 7 Dec I at last got a reply and has to forward the documents to Tanya Brown as requested by her.You can't email dire t so you go into the system again. I heard nothing again then on 29 Dec I phoned and the person found my docs went through it and told me all was there.I will hear from Tanya well on 15 Jan 2024 I phoned again then spoke to Gloria she che ked again said all forms are there she as she spoke to me said I'm sending to Tanya .but I can phone the next day and I can ask to speak to Tanya which I did only to be told she is not at work...I phoned again yesterday after 15 min got through only to be told her line is engaged but please give my phone number and Tania will get back to me.i did send an email this morning again they will reply I 3 to 5 working days.....that I will take in further..
