Address:

Shimoga, Karnataka, 577401

Order was placed on 2nd april 2016 and received a tracking number which said it will be delivered by 11th april. Then on april 18th send a complaint that product still not delivered. Received another tracking number saying product will be delivered with 5-7 days. Both the time fedex informed that only label was created but product was not provided to them.
When i asked for a cancellation, they are saying amount will refund you but today is 08th may, still now i did'nt get product or amount,
Also if i call customer service order inquiry, nobody picks up. I have to call their customer service product information for someone to pickup the phone and then they told me its already delivered but its very shocking, this is 4th time i am complainting but no use. what is this mebelkart.
