Jaxtakart — non/delayed delivery of product

Order id - 412040
I order a premium lava pixel v1 battery.
From last 10 days i am seeing the same message on "track order page"that my product has not been shipped. There is no update.
They promise to ship the product within 3 business day and deliver it within 7days for express delivery. But its not so.
I have already sent 4 mails to them on their email [protected]@jaxtakart.com but i got no reply from the jaxtakart team. I tried calling but they dont pickup the phone and switch it off later onn
Once they picked up the call and for 45 secs i kept on saying hello hello and there was no respinse from other side after that they didn't pick up the phone.

The biggest fraud they do is.. They dont have the product in the stock and still show it available on their website and take order on it.. And later they dont deliver the product.
Never use this site.
