Pathetic service................

I've submitted the same claim since the beginning of January, several times, in order to get a response. Diddly squat.............I've logged onto the website to see if my claims have been submitted - Nothing! The last claim submitted, according to Discovery, was in December! This is absolute nonsense! When resubmitting my claims I've requested feedback - nada, nothing, zilch. What the hell is going on???
