Don’t pay until the work is done.

A Belleville homeowner is wishing he or she would have heeded those words of wisdom.

Friday the homeowner responded to an online ad promoting a snow removal service.

A man showed up at the residence and collected cash at the door and promptly left without doing the job.

Belleville police warn people to be wary of online or classified ads.

The online ad in question was removed soon after the incident.
