harrassment

I have several payday loans overdue once i got one it was an endless cycle. I live in Missouri and I am trying to find out if what these companies are doing to collect this debt is legal. They come to our house and leave cards on the door if we dont answer, they call my husbands job even though he has told them not to they usually call all of our numbers cell home etc several times a day, and now they have been putting through our past checks to them almost 3 times a week and running up isf on our checking. We have an attorny and are thinking of filing for bankruptcy, we have already paid our retainter fee, so what can we do to get them to stop all of this? Is it legal for them to be collecting this way?
Thank you for your help
