Tradus — They cancelled my order and non refund

Address:

Hyderabad, Andhra Pradesh

I Purchased a item, ID: 3008451,Payment date: 21 JULY, Order id 3250126. But it suddenly disappeared from my order history. After sending 5 requests and 3 phone calls they said everything is fine and just a system issue. Then after a day i get an email of refund and they say it is out of stock. The mail says "refund in process".

Question 1: Why was payment accepted for a non available item?
Question 2: No provision for functional customer care?

After that is start getting automatic responses for each query sent. All they say is a server fault "We are facing some technical difficulties. ......".

Question 3: Server fault? What if my bank account/ credit card information was hacked from their faulty server?

After 3 days again i get an email that order has been refunded.

Question 4: Where was the refund made, i cannot see on my card that was used to make purchase, in addition to that they are not even replying to my simple email's that ask the mode of refund (credit card, bank, check etc). All i get is automated email in response to my query.

I have tried contacting TRADUS via the form at contact us page of their website with all details.
Email addresses i have contacted but received no response:
[protected]@tradus.in
[protected]@tradus.in
[protected]@ibibogroup.com
kavita.[protected]@tradus.in
[protected]@tradusupdates.in
Official Contact page (Preeti rai)

Numbers i have contacted :
[protected]
and their helpline number too which i got after speaking to the above contact but have lost in my redial list.
All they say is it will be delivered.

Question 5: If they say on one end it will be delivered, and on other that product value will be refunded. How should i convince myself for the type of service they provide and how promising they are after they cancel my order without even informing me and replying to my questions?

I have Spent 3886/- INR for the product
Over 2 days researching prices
Waiting 7 days for delivery
Then waiting again for refunds.
Over 10 days following up with them
20+ email conversations (one way only)
Over 8 calls to two numbers, answered just twice.
Will i need to go to Delhi/Gurgaon to take my refund by spending over the same amount i used to make purchase and time that's the most important, i guess.

TRADUS needs to respond if they are into business.
I have ordered products from international market from multiple sites that don't fall under the jurisdiction of our country but they had excellent support and reliability. That's what they call " business ".
