We had carpet installed in our house yesterday. A crew of 3 men did the work and then boss and person I'd set the appointment with showed up at the end to collect payment. We have now discovered that my husband's mp3 player is missing off his dresser along with the USB cord & direct line to a CD player. All this confirms to us that it's not been misplaced, but taken by someone who knew the parts they needed. Can I stop payment on the check to the boss for the install? What info do I collect from him about his crew in order to file a police report?
