Slow service and no communication

Absolutely pathetic service. I placed an order with cotton on 3 weeks ago. The parcel was received by Dawn Wing on the 19th of May. To date the parcel was only scanned into the cage on the 27th of May. I then called during this week and they told me delivery would take place within 3 days- fine. But that parcel status has not changed so how will it get to me in said time? I understand courier companies have back log due to COVID-19 but communication and service delivery is obviously not a standard upheld by Dawn Wing.
