Help. need suggestions

I don't have a debt problem, unfortunately my husband and I are getting divorced and he has maxed every credit card he could get his hands on and now is filling bankruptcy. I have two problems relating to this. The creditors have gotten ahold of my telephone number at my new home and repeatly call even though I tell them he does not live here, never has and never will. I also tell them I do not wish to have contact with him. I tell them very clearly to STOP CALLING. They KEEP calling. The second situation deals with two credit cards I cancelled, one in both our names, one in just mine. Unfortunately again, he reopened both of them and maxed them out. I am responsible for these, about 40,000 that will probably take 20 years to pay off. I closed them without a clause that both parties would have to consent to reopen. I don't know how he opened the one in just my name. But he did. Just wanted to let people know when closing cards out make sure to place this restriction on the card or your ex can make a call and get them up and going. Since the bills were going to his address I didn't learn about them until the creditors started calling. One good thing about them, I guess.
