All Eyes Over Here — bad product, no exchange no response

Looking at an instagram post, i ordered a pallazo set costing 1700 rs wherein she confirmed there is a exchange policy. Then the problem started. 1. The set which i received doesn't match with the post on instagram. 2. If i approach for a exchange then she gave me other contact number. 3. The other contact number says they are not replated to them. We can't trust if they have joined hands and are asked to behave this way. 4. After all this episode there though the lady is online she is not replying. We have been cheated royally, i get so annoyed when i see there post everyday. I don't know how many more will be cheated
