Royal Enfield — Chain sprocket teeth broken rear wheel

I bought RECLASSIC 350 BS 6 CHESTNUT on 7.9.20. Here I would like to inform you that my vehicle rear wheel chain sprocket broken while cleaning I noticed that, in this regard I called RE support team toll free number to assist for claiming warranty (replacement of rear wheel sprocket) i unable to get enough information. I informed about this issue to service provider also. Hence I done 3 free service within the period, also chain sprocket lubricated every 500 km, vehicle rided approximately 9500 km till now maintained properly, help me to get the issues solved. Thanks
