PAYING FOR A SERVICE, FOR NOTHING

I ordered an item from a company and was not delivered on time,in fact it was delivered only after 2 days,while waiting for the for 3-7 days delivery. According to the delivery schedule my parcel was dispatched on the 21st of April and sat in linehaul on the 24 of April 2021(weekend)I then sent mails about my delivery on the 29/4/2021... before this not one person from DSV had the courtesy to contact me about my delivery being late.I was then sent a mail stating that I would receive my parcel in the 29/4/2021(that did not happen) Order number : QNGBT***5 I then only received on Friday the 30 of April 2021 at 16:10pm. When I asked Mary Mmatli from the smart locker suppprt about my late delivery and the refund about my delivery fee that I paid, I did not get a response.so why are we being charged delivery fees and told it would be delivered between these days and does not happen?
