My employer cancelled my health insurance policy after I made several attempts to call and could not get through. I mailed my payment in before the deadline and they sent it back on week after the deadline. I am disabled and was due to be eligible for COBRA. Can they do this. I have special circumstances that prevented me from being informed on any changes made to the health coverage, and was not informed. I called my boss and got no where.

You are more likely to get helpful responses if you post your question in the section called "Health Plans (Including COBRA and HIPAA)"

I think you also need to provide more information in your post, too. For example, you say you weren't informed of any changes. What changes were made? Also, you don't mention if you were at the end of your approved leave time. You may get more information from your human resource department (that's what they are there for) than your boss.
