I purchased XXXX months of medical insurance and it covered everything but a XXXX co-pays in XXXX 2014. This was was single coverage between XXXX jobs. Several months later I received a letter from collections for over {$300.00}. It appears the medical clinic lost the right information from my insurance and decided to bill me directly. The collections company is suggesting this is my fault even though I sent them proof of the coverage that and proof of payment for the coverage. I am not sure what I did to get this sort of harassment.
