air conditioning and refrigeration

we are so shocked at the people they employ, rude, aggressive, foul language, smoking in our offices, we asked them to leave,1 of them, a tall filthy-looking guy, got quite aggressive. This is the type of businesses that private individuals including businesses should avoid. Our staff were really very scared. Emails to this business, no response so far! It seems they ok with uncultured staff putting the safety of their clients at risk?
