It's hard to say because you don't say what kind of I-130 case this is and what country you are from or what status you are now if you're in the US. Nevertheless, if you have an attorney it is his/her job to try and resolve the situation. We can not advise you of you already have counsel.
If your lawyer has lost your trust you may fire him or her and seek new counsel.

The following information is procedural in nature, is not intended to create an attorney-client relationship, and is merely for information purposes.
The NVC will send the documents to your attorney via e-mail. You should be able to call the NVC and find out what your case number is. If you have lost trust in your lawyer, you can fire him and remove him from the case - and then have the NVC send the documents to you. However, you should make sure you have not misunderstood things before doing so. In many cases, the NVC will also mail or email you a copy too; ask the NVC to send you a copy directly.
The NVC normally sends the visa application documents within two months a visa number becoming available for the case. You can view the visa bulletin by going here: http://travel.state.gov/visa/bulletin/bulletin_1360.html
Additionally, in a few types of cases the NVC does not send visa application documents.
Visit your attorney and ask him or her for more information. Sometimes attorney's get lost in all the clients they have and a case without a firm deadline is temporarily misplaced. A little friendly nudge is sometimes required to remind an attorney about your case.
Finally, keep in mind that you have one year to respond to the NVC from the date that they last sent documents to you or your attorney. If you do not respond within that time frame, your case may be rejected automatically.
