Royal Enfield — full payment made, but not delivered till on the 10th day

Address:

Alappuzha, Kerala, 688522

As per the directions from riders motors alappuzha, i made full payment for gunmetal gray 350 classic (Rs. 182225/-) on 2nd may 2019. They assured delvery within 4days. But not delivered yet. When i contacted, they didn't repond in a positive way. They casually talk that delivery may takes 20days more.in april i made the booking and april 29th riders motors demanded the balance payment as the vehicle arrived. It was a great disappointment for me and lost faith. Do something judiciously.
Thank you
