BAD SERVICE ON GENERIC MEDS

What a bad service. phones goes unanswered and one is kept on hold for eternity, claiming to have high call volumes while my life is at risk. My doctor prescribed a medication for me which is 20mg a day. they gave me a generic which is 5mg a day. way way less that what my doctor recommends. the medicine makes me sick, the medicine is not helping the situation at all, instead it puts my health at risk. my attempt to have the medicine replaced fell on deaf ears. No ne is interested..I have resorted to taking 4 tablets a day to get to the required 20mg out of desperation..i might be overdosing not knowing..
