Ask Me Bazaar — Pathetic service no tracking option and order cancelled without intimation and amount not credited

I have ordered a Camera tripod and paid through online banking.Once ordered is placed got a message saying that your ordered is received in will be shipped.

But after 2 days got a message saying that your ordered is cancelled and the amount will be paid after 5 to 6 days.

There is no tracking of the order in that site. How come a e-commerce site can sell product without having tracking option.

How come they can list the product where there is no sufficient product in stock (Still the product is listed).

How come my order can be cancelled, Are they earning interest by keeping the paid money.

It is pathetic service.
