Delete 10.404 rows from a spreadsheet report

I have 3 voice broadcasting reports with a total of 16.175 calls and their "Attempt Status". The job is delete all the rows from "answered calls" (rows with red line in attached file) from these reports so at the end I will have only the rows for "No Answer", "Not Available" and "Busy" calls. The reason for that is that I will use this new report to call just the numbers that could not be reached. You will have to delete 10.404 rows with answered calls. At the end these 3 reports should have together 5.771 rows with "No Answer", "Not Available" and "Busy" calls.
