I have ordered a "western digital blue wd40e31x4tb sshd hybrid internal drive" from amazon on 4th of march, 16, but instead of that i got a piece of stone i so shocked. I complaint to the customer service they said when the product was complete when left their fulfillment centre. But i didn't get my product. They think i am lying to them. I told them that i can provide pictures and made so many complaints but they didn't reply after that, even block my number and didn't respond to my mails. Where should i go?? I have spending a huge amount money for that product, and didn't received the product too. I am just middle class man. I want my money back. Now its going to be two weeks, didn't receiving any information. Neither they receive my call nor they answer my mails. Pls help me out with this.
