I placed order number *** and paid for it

I placed order number *** and paid for it. The instructions are that Amy at our offices is to sign for the parcel. It was meant to be delivered Tuesday 6 May 25 but wasn't. They then scheduled it for delivery Thursday 8 May 25 and marked it as delivered. However Amy at our offices never received the parcel. We checked our CCTV footage and confirm this. I tried to log a query Friday 9th, again on Monday 12th, and now again Tuesday 13th, but their system does not give me any email confirmation that a query was logged. I'm very desperate and don't know what to do. Please can Takealot contact me. I'm hoping they will get this message. They have no phone numbers listed on their web page. Thanks.
