SSI at 65 dispute between call center and local office.

Hi, folks. I'm in the middle of a disagreement between SSA's national call center and a local SSI 'specialist'. The national people believe I can apply for SSI aged benefits 2 months before the month of my birthday in March (apply in early January), while the local 'specialist' has cited various dates ranging from March 1st. to after my birthday on March 29th. This is complicated by the likelihood that Congress may act to restrict, reduce or eliminate SSI entirely as soon as possible, and by the 'specialist's seriously prejudicial and conflicting statements. Neither the national nor local people can cite the actual rule on SSI applications or any case law. I've already been turned away from an appointment today, and been on the receiving end of an objectionable comment that 'SSI recipients sit around in bunny slippers'. Amazing, but now what?
