Bad customer service from Metropolitan Life

Metropolitan Life has no customer service at all. I took out a policy many years ago with Momentum, which was transferred to Metropolitan when the companies merged (this was without my knowledge or consent). Lately I have been trying to find out what this policy is about, and how I can make changes to it. When you phone their customer service number, they tell you that you cannot speak to an advisor, but that an advisor will call you back within 3 days. I received a mail 3 days later with a letter attached. On this letter it gives the policy number, my details (with my age the date I took out the policy), and details about how much it will pay out should I die. But there is still no way to contact them to ask them to make changes. I have rep**** to the mail asking for help. I have phoned the customer service number. And I have tried Momentum. But apparently it is not Metropolitan policy for advisors to speak to clients directly.
