Zivame — Zivame online app

Zivame app is worst app i have ever used. It does not allow me to cancel my order and after return it doesnot refund money to my account instead we get money inform coins .It does not show the order delivery status correctly and no one responds in customer support. I trusted the brand and paid before otherwise I would have kept COD.
I am very upset with app and unhappy with service please respond back Asap.
