LOCK434479 customer complaint

Good day I ordered a shoe at Zara Online. Cool the shoe was delivered and handed over the shoe to the courier company ( The courier guy). The parcel was suppose to be delivered to me by the 0701/22 as I ordered on the 22 /12/21. The Courier Guy sent an email on the 11/01/22 very late with a lock number LOCK434479 informing me that the parcel will be delivered on that day. None of that happened then I track my parcel only to found out that they claim to have tried delivering it but no one to receive the parcel and return to the warehouse two times. They never cam even once. I decided to phone them then they **** and say I didn't put contact details on the order whereas I know very well that you won't proceed your order online without a contact number.
