Shop CJ Network — fraud: shop cj delete all account and product details with pending transactions

I bought a product from shopcj in the month of sept 2017 and requested a return immediately due to poor product quality. It took 3 months for them to take back the product. Then in order to get the paid money back we had to give multiple calls and email to them yet never got back the money. Today on checking we found that all my account details and transactions related details are deleted, including the product no.. And everytime we ask them to forward the call to the supervisor they put us on hold and we never get a chance to connect.
With my experience i can only tell -
This channel and site should be closed and ban from our country...
They are cheaters who only harass the customer.
