Flipkart — Very pathetic service from Flipkart fraudulent activities

I ordered GNC creatine monohydrate from Flipkart and paid rs 788 . But on 23 September i received wrong product that is Octavius kadak Asaam tea (rs 600 printed on it) I raised the request for replacement. Earlier the replacement date was 29 September then it was shifted to 5 October, then again date was postponed to 7 October.

On 6 October all of sudden i received a message that your Replacement has been cancelled.That’s also without any reason.I have been requesting Flipkart agent to look into this matter since I was delivered the wrong product, Its almost a month but No action has been taken from Flipkart to solve this issue, They have only made excuses.I will share the screenshot with you. Please help me how can i get my money back.
