What should I do if I haven't received a response from the SSA after multiple emails regarding my coverage?

The user has been unsuccessfully trying to contact the Social Security Administration office in Manila for over six months through email, without replies. They are seeking alternative methods to reach out without incurring high phone bills through calls. Responses from the community include suggestions to have a US congressman inquire on their behalf, possible landline packages to reduce costs, and advice on using the SSA's callback system to avoid long hold times.
