Lost Package

I ordered things online , received a message from that they have been delivered on Monday 03.04.2021, I actually thought the items will come in one package to my surprise another message was received Tuesday 04.05.2021, I went to Clicks in Morningside (The Wedge) to collect , the lady that was assisting me was helpful though, she indicated that she can only locate one parcel, the one received by them today , the one they received yesterday is noted in their book however the package isn't there

she then called the person who signed for one parcel yesterday a collection by another client, to enquire if she indeed gave the customer the correct package

the first thing the lady said to me was didn't you collect the package

I indicated I didn't- I mean I wouldn't be there if I did

the person searching for the gift was the lady who initially assisted me more than the one who assisted the other client with the collection

she however took my number and indicated she will call as soon as they locate the parcel

my Question is who will then pay for the missing items , will clicks reimburse me the money I paid for the lost package?
