Flashstar Commerce — not able to deliver the product in time

Flashstar commerce seller seems don't worry about once the product is shipped from their store. Its very disappointing that after too many negative reviews on them, they didn't choose right delivery service partner. In my case I ordered a product on flipkart during recent bigbillion days and made payment on[protected]. Flashstar commerce started processing the product on[protected] and they processed with Ecom xpress courier service on the same day. It took almost 6 days to deliver product from Hyderabad to Chilakaluripet (which is just 300km distance). The product was lying in the Visakapatnam Hub for 2 days, and Vijayawada Hub for 2 days, without any reason. The product was purchased by me to gift my family member before Dussera festival. Today festival also completed, but I don't know where my product got stuck up. It's really shameless act by Flipkart, Flashstar commerce and Ecom Express people. I am not going to recommend anyone this seller.
