Zepto — Order Was Marked As Delivered But Was Not Delivered

First of all Zepto this is not the kind of behaviour i would expect first the order which was marked as delivered and was not delivered to me and i called the delivery partner he was not picking up the call and then i goes to in app support where they wasted my 45 minutes then started we have throughly reviewed it was delivered to you but as i said it was not delivered to me so i called and then the customer support executive was talking rudely to me i paid 413 ruppes for that order which is not a small amount so i request zepto to look into this and provide the refund
