[Resolved]  Maxbhi / Elcotek Telecom — Defective display

I have ordered a display for my phone from this website. They have sent a defective product. Ok no problem. But they should replace or refund the money. I have also placed the replacement request. But it does not even move to next step. But they are not even taking the calls. I have requested a n number of callbacks. No call back is attended. I don't want to say any word. Please do the needful. Thank you.
