Caterer ghosted me?

I have been in contacted with Weber Grill in the Schaumburg area. We communicated for a month before going for a tasting in early March. She sent the contract via email. We sent it signed back 2 weeks ago. I had emailed and called her 2 times since sending the contract. The manager told us that she has been in the office all week. I'm not sure why she hasn't gotten back to me. I'm a bit concerned.
