Amazon India — Unethical practice by seller on amazon.in and no support from amazon

Address:	New Delhi, Delhi, 110058
Website:	AMAZON.IN

Regarding order xxx-xxxxxxx-0969957. Seller name is "shop your world" had cancelled the product with an excuse that they received it in damaged condition but the fact is same seller is selling same product at higher price which clearly amount to opportunism, cheating and unethical practice on which amazon seems to be having no control.
Despite couple of reminder from amazon, seller hasn't bothered to contact me even one and amazon also seems to be no mood to take any action against such seller.
Now this is virtually to force a customer to buy product at higher price. Now every where price of this product is high and i have to bear loss because of this malpractice.
Product name:mio fuse heart rate training with activity tracker, large (Crimson)
Price at which i ordered is 6192
Current price by same seller on amazon.in is 9301
Elsewhere it is above 11000.
Attached pic clearly shows that seller still has product available and sellign at higher price but refused to deliver it to me with false excuses.
