BAD, BAD, Customer service

Such bad service. Ordered a parcel from Zando on Tuesday. Got an sms this morning that it will be delivered via CourierIT today. Come 17:00 I call the customer care which they took my waybill number then decided to put my call on the side to have a conversation with her colleagues, I literally held for 5mins. I had to hang up and call again to only find out the driver had too many parcels today and my parcel will arrive on Monday. How about informing the client? I am seriously VERY disappointed in your service,.
