Lost Parcel - Consumer Complaint for PEP STORES

I sent my parcel at Pep Kolonade Mall on the 22 July 2020 and they lost my parcel in their store. Since today I haven't received my refund or my parcel back there's no one person taking responsibility for their actions and they don't care. I'm the one going one and down because I want answers and I want to be refunded for my parcel. I want my parcel back or my refund and there's no update or feedback on what they are doing on their side I'm very angry and furious right now.
