After you file

I see you say 'generally' amended taxes go back only up to 4 years. How do I appeal that I have tried to use the specified contact in Manila to support me in this and was not advised correctly.  I finally sorted out the amended due taxes and the paid amended taxes was returned saying it was no longer viable. Due t this I am 2 credits short of the needed 40 credits and CANNOT get signed up into medicare before retirement. How do I appeal this extenuating circumstance being overseas and ill advised and repay and get the 3 credits that my amended taxes would afford me?  Please help with any contacts or resources which can support my efforts. Sincerely;

Laura S
