Have you received any notification of refusal of SWA? Have you contacted the officer who took the SWA application to request a written decision on your application?
I'm a bit unclear what you mean about "an entry under my PPS Number which another staff member quoted". You are dealing with 3 different scheme areas (Supplementary Welfare Allowance, Disability Allowance and Carer's Allowance), which area gave you the information on the "entry under (your) PPS Number"?
Disability Allowance and Carer's Allowance applications can take several months to process, so it would be unlikely that you would get a decision on these claims in 8 weeks.
