Non delivery

I sent a parcel with RAM, they said it will be delivered on 09-07-2020 but that did not happened. Upon tracking it I saw a message "UNSUCCESSFULL DELIVERY IN Kimberley - Re-attempt delivery". That time the intended receiver was not contacted at all. The following day which was 10-07-2020 I kept on tracking the entire day and late at night around 21h00 I saw the following message, "UNSUCCESSFULL DELIVERY IN Kimberley - UNAVAILABLE HOME - CONTACT NOT AVAILABLE."

I have included the recipient's contact details on the waybill and I notified her to be on the lookout. She confirmed that she was home the entire time and she didn't receive any call from RAM. What is the point of including the mobile phone numbers of the recipient/receiver if RAM is not going to contact them should they have difficulties making a delivery? What evidence is there to proof that RAM indeed went to the recipient's premises?

I find this very unacceptable because we trusted RAM with a very important parcel and now it is not delivered.

Tried to call their customer service number and was holding for more than 30 minutes without answer and their chat service is not working.
