Jaxtakart — no response to my cancellation request

Address:	Pune, Maharashtra, 411033

I placed order to purchase battery for my karbonn a92 mobile phone. However after deep inspection into the details, i found out that the battery displayed on their website is for karbonn smart a92 mobile. The battery specifies 3000mah capacity in the description of the product for the above phone.
I require battery of 1600 mah capacity.
I wrote them email on their official email address to cancel the order and refund my money.
They only send standard reply as we will get back to you in 24-48 hours.
The phone is kept engaged all the time. I am worried about the amount paid and there is no movement either for refund or clarification.
I paste below my order details from my account on their website:-
