Can you sue an employer for making promises of 90day and 180 say raises

Almost all employees have been verbally told they would recieve 90 day raise and 180 raise. And none of us have recieved a raise. They also advertised a 90 day and 180 day raise on indeed but have since taken it off indeed. But they have told all employees we would get the 90 day and 180 raise. Yet when it came to the 90 day mark and 180 day mark for some when inquired on the raises they refused to give anyone raises and said they dont do that and only give a raise once a year. But told all of us in the interview before being hired we would in fact receive 90 day raise and 180 raise
