Undelivered Parcel

A parcel was collected by the courier guy on 27th March 2023. today, 8th of April, the parcel has still not been deliveredand this after receiving a message to say that the parcel is out for deliver on 6th April. I have received a number of calls on 6th April asking whether I have received my parcel with everyone saying they will look into it and call me back. That is where is has ended. When I check with the online store I purchased from, they have been notified that the par el has been delivered. Shocking.
