Amazon India — Seller is a fraud

Address:	Bangalore, Karnataka, 110026
Website:	www.amazon.in

I am one of the regular buyers at Amazon.in. This is regarding Amazon order no.[protected]. I placed the order on 10th January 2017, paid in full but haven't received it till date.
The vendor "Liveyoursport" is making lame excuses by sending me mails (after a month) that the product is not available and there was a price problem when nothing as such is true.
Just that now since the price of the product has increased, the vendor wants me to cancel the old order (placed at lower price) and place a new order at higher price. He is a fraud.
I have told him that I will not cancel my order and will not take the refund.
I want my product to be despatched to me immediately.
Please look into this serious matter and contact me for any further information

Thanks
