incompetence and poor administration

I just joined this medaid, ignored negative reviews I saw online as I gave them a benefit of a doubt. Only to also be a victim myself. I have mitral valve disease that I disclosed before joining and really asked several times if they are sure I wont have any waiting period, which they convinced me that I must relax cos I wont. This week my heart condition complicated, felt like I was dying, I rushed to closest ER WITHIN THEIR NERTWORK HOSPITALS as a matter of life and death, then this med aid refused to cover in full hospitilisation, saying I used a network hospital that only for day procedures and not for admissions!!! Then cardiologist had to transfere me to their recommended hospital, now at their very own "nertorwk hospitals for admissions" they today DECLINE my heart procedure. The procedure my life depends on, apparenly reason being non-disclosure what what! So they don't care about my health, current emergency but their own processes, I fail to understand why did they not do those non-disclosure nonsense when they took me knowing well I have a mitral valve disease which was not any of the list of their chronic diseases when took me in. I mean they made me leave my good med aid and trust them to dump me today in such an emergency situation. If anything happens to me, if I don't survive this medhelp is the reason for my death.
