State Department Federal Credit Union (SDFCU) Customer Service Issues

I have a question. Firstly, I would like to clarify if there are any charges for the information and advice provided by GetHuman. Additionally, I am seeking guidance on how to establish credit with no prior credit history. Specifically, I am looking for recommendations on the best credit cards for individuals in this situation, such as secured credit cards. I initially thought a secured card would be the most suitable option for me until I noticed the extremely low ratings of the source recommending it. I am concerned about the lack of customer service support for the secured card offered by the SDFCU. GetHuman was the first search result when I looked into contacting customer service for this particular secured card.
