Urgent issue with test cases

You guys don’t have rigorous test cases. I want compensation. Other websites like GeeksForGeeks and LeetCode have about 400 test cases per problem. Your test cases are so bad that they accept incorrect or partially correct solutions that don’t cater for all possibilities. I put up a post a few minutes ago but you guys deleted it so fast so that no one will see my complaint! Fix the test cases by adding as many handcrafted and rigorous test cases or compensate us for this poor course!
