If you are using the correct term, if your bankruptcy was "Dismissed" that means that the courts have decided to no longer let you continue through the bankruptcy process(such as you failed to meet one of the provisions).  It also means that the creditors have the legal right to continue with their collection efforts.  It also basically voids any "Payment Plan" and you could still be held responsible for interest.

Now, if the bankruptcy was "Discharged", the courts have said you have fullfilled your obligation and the creditors are bared from attempting to collect on the discharged debt.  There are special rules about secured loans that MAY be coming into play here. 

But what did your attorney say?  As since this is part of the BK they should be contacting either the creditor and/or the courts for possible violations.
