That's a very disappointing attitude to have encountered. My experience of dealing by phone with a few different government departments has been largely positive where attitude is concerned. Admittedly the baseline has not been very high in the past. Knowledge seems to be slowly improving as is the quality and extent of online information on Gov.ie.
However there are still gaps where clarity is concerned. One example is that I've been unable to source the revised table of benefits for the State Pension Contributary Average method. We have been told what the new full pension is but not the lower levels, as far as I can see anyhow. Maybe somebody else has been better able to track down this information?
You probably know this already but for the sake of other readers, if you decide to have another go, I'd suggest approaching it slightly differently. Rather than asking for information specific and personal to you, ask a hypothetical question using your own data. For example, in relation to the over 65 payment, ask how does one qualify for a payment? Expand the conversation with questions that help you draw a conclusion that is likely to apply to yourself.
Sharing your de-personalized PRSI record here will probably produce several responses regarding your likely pension entitlement.
