Shocking customer service

I placed an order for a desk on Thursday and booked a delivery for the next day at an extra cost. Not only did they not deliver my parcel (had someone sit at home all day) but I received a notification on my delivery status that the delivery company had received insufficient delivery details despite my full and correct address being reflected on the order advice. I phoned Superbalist.com concierge on Saturday morning to enquire what the hold-up was and was told that the parcel had been dispatched to the incorrect hub but that they would get back to me and let me know when I could expect delivery. Needless to say, that never happened. It is now 10h15 on Monday morning and I have just phoned them again and they still cannot tell me when I can expect delivery. Again, they have promised to get back to me. I will not be using this service again as clearly client service is not a priority.
