Myntra.com — Wrong information provided

I have ordered 2 same nautica jacket from myntra out of which i want to cancel one of the jackets but due to some technical problem on the website i was not able to cancel one of the jackets.So to cancel one of the jacket i contacted customer care to cancel one of the 2 jacket and the customer care member cancelled my other product in the basket without telling me the same together with the jacket.Now after telling my problem they are saying they are sorrry they cant do anything.Its highly imcompetent negligence by providing incomplete information to the consumer.Kindly take action asap.
