Royal Enfield — Engine abnormal sound and head gasket leakage

Address:

Kaizen Motors, Vytila, Ernakulam, Kerala

I own a RE Himalayan which was purchased on 21/11/2019 and within one year there was an oil leakage from the head gasket. I reported this complaint to the authorised RE workshop ( Kaizen Motors, Vytila, Ernakulam, kerala) and they assured me that they will rectify the complaint. But the next day when I went to take the delivery after service I was wondered what blunder an authorized dealer had done in rectifying the complainant. They haven't changed the head gasket, instead they had pasted some sealant from outside( which I think is only a temporary solution)

This isn't acceptable from such a prestigious company. I kindly request you to look into this matter and kindly do the needful.
