Amazon India — order being returned without my knowledge

Address:	560052
Website:	amazon.in

Hello, my name is sachin m. D, my area pin code is 413501 i had ordered a product from amazon on 11th sep 2018, order #[protected]., at the price of rs.3870, and the package was in transit as usual, then today on 16th sep, i saw the update that the order is being returned back to the seller without me knowing it, and i didn't even cancel it. And now the price of the same has been increased to rs.4000, which looks clearly like a trick to me, to make me pay more and cancel the existing order.

I contacted the amazon customer service, three different times, they just told me that as this order is (Cod) cash on delivery, we cannot do anything about this, and you will have to buy it again in new price..! Which was totally injustice to me, and fraudulent, this is not my fault at all and they have a fraudulent policy which is not doing justice at all.. I'm clearly being cheated and the seller tricked me to pay more now. The seller is gym food nutrition, on amazon.
