Bills entire backlog at once

I updated my income information for the Keycare Plan (end last year already). I didn't hear from them at all and looked at my documents again before I contacted them. I noticed a mistake (I filled in my monthly instead of yearly salary) and rectified this mistake. Discovery then proceeded to up my premium (which was expected), but also subtracted what I owed them for January and February as well as the new monthly premium all at once, without prior warning.<br> <br> What happened to letting me know that I owe them money? Since when can companies simply take money out of customer's accounts without any regards for HOW THEY ARE GOING TO SURVIVE THIS MONTH!?!?<br> <br> I contacted them to try and sort this out, but the caller and her manager \simply can't help me"so I consequently ended my dealings with them permanently.<br> <br> Now looking for a new healthcare provider. Hopefully they aren't all callous greedy ***s."""
