It sounds as if you didn't answer to their letter. When we sent our petition, I took a long time to start the visa process. I mistakenly thought after the petition was approved I could have waited as long as I wanted to and they sent us a similar letter that stated if we wouldn't pursue the visa petition within a year it would be canceled. You need to write to them explaining the situation that you have not received anything from them. At that time I sent them an email and also a written explanation with my signature and the date. Try to call them and ask but in any case write an official letter with the explanations and send it as a registered letter to make sure they receive it.
