Was doing touch and go's on runway 4L. Told ATC that we were going to be a full stop landing and were told to extend the downwind and contact tower [on a different frequency]. We contacted tower and they told us to turn base and that we were cleared to land on 4R. While we were turning base; I looked up and saw Aircraft Y about 100 feet above us and probably about 100 feet horizontal distance. The tower was asking 'Aircraft Y do you have traffic in sight' and getting no response. Aircraft Y continued to fly above us on base and turned final on top of use while continuing to ignore tower's calls. I told tower while we were on base 'There is Aircraft Y flying right above us'; their response was to ask Aircraft Y if they had traffic in sight. Near the end of our base leg; while we were turning final tower asked us if we were on downwind still. I responded that we were on base and they told the Aircraft Y to climb to 3;000 feet and overfly the runway.[Company of Aircraft Y] is a danger to the skies and too many of these incidents happen on a daily occurrence. They need to be looked into due to the disregard of English proficiency which comes into play for many of these incidents.
GA pilot reported NMAC in FFZ pattern with unresponsive aircraft. Pilot reported this as a common occurrence in the area especially due to lack of English proficiency.
