I decided to quit as Kosher4u customer, recently they sent me a broken package without any refund.
The parcel was returned back by their courier (UPS) (before its arrival at destination), due to the broken bottles that damaged the entire package.
They have resent me the same one with 2 broken bottles inside. They refused to refund me any amount, since they consider are not responsable for the conditions of the package at the arrival. What is very unusual within e-commerce good practice. Furthermore, it has been dangerous to open the shattered box with pieces of glass inside. They declared that resend again the parcel has to be considered as a favour. Immagine, something I paid and never received.
