Describe your issue

My rating is droped from 1100 something to 1000 for a cheating case but in that cheating case it show me that ansariahmadfaraz28@gmail.com cheated 4 times from rcp_fy_24002 (both are me first one is my registered email and second one is my username ) so my rating drop by 270 but it drop around 600 and then in starters 165 it show my rating as 450 then I solve 2 problems successful and score 200 but my rating drop by 100. Please immediately solve this problem so I restart my journey on CodeChef. That’s a humble request from me. Thank you
