My grade 4 wont come back

Hello so i was a grade 4 for but a glitch with the stering controls at calibration which had made my plane nose dive and crash reduced my grade to 3 its been a week now but it should have came back but it hasnt i looked to see why and some how the game has reduced my landings to 66 compared to the 100 i just had is their a way to fix

The landings are in chart for 90 days only. If it dropped down, you’d have to get your landings back. Sorry!
