Answer: c. I and III
Step-by-step explanation:
Dishonesty in business is a very big issue as it can lead to mistrust and can damage the reputation of a business which would affect profitability. If a company has treated you dishonestly and unfairly, it is prudent that you report the activity to their corporate consumer department which acts as an oversight body for such actions.
You should then report them to the Better Business Bureau if you are not satisfied so that the BBB can make sure that others are not treated as unfairly as you have been by marking the company down.
