MetLife is unresponsive to my emails but expects me to respond to theirs

I have a disability policy through work. I have been receiving payments for the past 9 years. After the first two years I stopped seeing a physician as I suffer from multiple radicuopathies after two unsuccessful surgeries I’m unable to sit or stand for a short period of time. Recently, Metlife has sent me their usual annual forms which I respond in writing that I am not required to be under a physicians care after the first two years and that I am not, and therefore cannot provide them with the information. This year they have conditioned sending addtional notificiations until the “final notice” within 15 days to respond. I have asked them to tell me what I am doing wrong. What can I do and they refuse to answer my responses. They don’t want any other informatoin such as pain management, they are only interested in a physician’s assessment. Metlife does have the right to send me to a physician for evaluation under my contract but they have not indicated that they wish to do so. Shouldn’t they be requried to have information that is contrary to my disability, or at least seek that information before simply terminating my benefits? They have never disputed my claims in the past. I have insisted that all cooresponance bein writing after one of their “managers” wanted me to lie to my doctor in order to acquire information, and then wanted me to have my pain managment doctor commit a felony by filling out the forms which is not qualified to do so. That’s when I said, put your requests in writing from now on. Since then, there have been two or three of the annual physician requests but no responses to mine.
