No delivery for days

I placed the order with spree a week ago(***) & from Friday I have been emailing to enquire about my order, the response I got is that the courier has confirmed that delivery will be done on that day but @ the end of the day no delivery. I emailed again today, (Monday) still got same response\order confirmed for today's delivery".no delivery again as I am writing this complaint. I requested the waybill & courier number so I can follow up & track parcel but no response. Service @ Spree has gone from bad to worst. Pain in the back while you spending money. Bad."""
