Update on Survivor Benefits initial ineligibility

About a month ago I was strongly encouraged by a SS rep to not apply for survivors benefits because he said I wasn’t eligible or entitled. Redditors assured me I was. Today I had a follow-up, and I’ll be receiving the benefit. I’ve shared additional info on the original post here: https://www.reddit.com/r/SocialSecurity/s/8oHQ9Xi1A4.

Who should I report the original misinformation to, other than the supervisor? Perhaps my senators? It could have cost me thousands and thousands of dollars, and others in this sub seem to be getting the same misinformation. There must be so many people who just accept the incorrect information and are denied legitimate benefits.
