acknowledging withdrawal of this application - Status

Hi ,

My employer has applied h1b, i have received status as,

“On January 23, 2014, we mailed a notice acknowledging withdrawal of this application or petition I129 PETITION FOR A NONIMMIGRANT WORKER. If you have not received the notice within 30 days of January 23, 2014, contact our customer service at 1-800-375-5283. If at some point in the future you wish to pursue the benefits provided by this application or petition, you must file a new application along with all applicable fees and evidence.”

But, my employer is saying they did not withdrawn the case. Could you some one help on this?

Can i use same quota and submit proof again.

Thank you,

Senthil
