I’ll share my story. The IRS incorrectly sent me a fine for over a thousand dollars claiming I had filed late. I tried calling them 9 times on different days to dispute it. Within a minute of opening, end of day, middle of the day, didn’t matter. Not even a wait line, just “sorry try later.” I finally gave up and paid the damn thing then got a refund for the fine over a year later when I guess they figured out it was…
Literally, I've learned this lesson the hard way. The moment I have to wait more than an hour or so to figure out a government service or agency, I immediately lodge a formal complaint with my representative. They have a large staff dedicated to constituent services, and they have internal connections. They also follow up, and if the agency isn't doing well, they track it.
I've literally been begged by federal agents to leave good reviews with the congressman in order that they don't get their budget cuts. It's a welcome change of pace to be speaking with an agent that wants to help me.
As an example, my son's name was mis-spelled on the birth certificate and thus social security card. We waited for three hours in an SSA office to change it but the woman did not want to help us at all, and insinuated we were committing fraud.
I had it. I called my US representative and my two Senators and e-mailed them a full portfolio of the details. Within a day, I had their office calling me with a special SSA representative on the line. They were able to make me an actual appointment for next day service at the local SSA office speaking to a much more intelligent SSA agent, who was so friendly and helpful, it was almost unbearable. The best part was, I didn't have to even wait in line or at the front desk. She took my materials, told me she will personally investigate and get back to me. Within a day, she called me back, had everything figured out and had completed several steps of the process for me.
In sum, never deal with the agencies if it's becoming antagonistic. Contact your representative. It is literally their job.
