Death claim bad service

We have submitted a death claim on 24/07/2019, all relevant documents and beneficiary details and claim forms were duly submitted, when I contacted them on Friday 2 August I was advised that it has been disinvested and payment will take place early this week, yesterday I received an email advising all beneficiaries needs to make the same choice, either disinvest or transfer, all our forms were completed the same ( Disinvest option). I called them again after receiving the email and was now advised that everything is actually in order and it will take another 2 to 8 days before they can pay out to us. When you phone in it is a different agent all the time and seem to give different feedback. We need the claim to be finalized this week as being advised on Friday.
