Day light *******

I moved to a new employer and my plan with Discovery had to cancelled but I still continued with Discovery under the new employer which they also subsidize. Now I am being told that I have to take pay a certain amount of money for the rest of the year which did not make sense, according to my knowledge if there is any savings left I get compensated but this time around I owe them I feel it's a day light *******. They don't even consider that I have been with them for 11 years consistently. I am considering changing my options to a different service provider that my new employer offer I am not forced to be with Discovery.
