Flipkart — Damaged product received and now no response from Flipkart

I had ordered this Bluetooth earphone by anker sound core liberty 2 pro at Flipkart for 9009/- rs but when I received the product and I opened the carton that had the box within it .. the box was dirty, seal was broken, when I opened the box the plastic casing within had a broken seal, the pods were smeared in dirt as it they were lying around in some dirty corner of the seller shop .. I asked for a replacement, Flipkart said the seller doesn’t have a replacement so we ll request a return and a refund .. but now Flipkart is doing nothin but giving me new dates everyday .. it started on the 12 th and it’s 20 th today .. n now at the customer care when I ask them to transfer me to a senior they put me on hold and then disconnect .. it’s such a helpless feeling coz u don’t whom to approach now
