Hello! When I began to receive a large number of spam calls, and could not do anything about it, I decided to use the Robokiller application, which was supposed to help me with this. After installing the application, I did not see any special changes. At first, I wanted to call the
robokiller phone number but then I decided to write to the support service. They answered me the next day, and they wrote in detail how to make settings specifically for my phone so that the application works effectively.
