british airways treating employees unfairly

I work in BA Gurgaon as customer service representative. last month my company added a new parameter to deduct our incentives by adding "Survey Trigger Percent" and "Survey Received Percent". We are suppose to dispose calls which will trigger the survey but If the customer is not filling up the form even after opting it, we will get penalised for the same. Imagine working your ass off round the clock and if a customer is not filling up a survey form you will not get any money. How bullshit and unfair is this! I used to think CallBA Gurgaon cannot stoop any lower but they literally will do everything in their power to deduct incentives for which the employees work so much! They will send you warning emails too if the customer does not fill a survey and threaten to throw you out calling it an integrity issue.
