the worst customer service i received in my life

I received a sms from skynet, informing me my parcel is out for deliver on the 9 December 2024. i have yet to receive my parcel which requires a valid SA ID to receive as it was a government document. i have yet to receive my parcel, i emailed and tried calling, but over the festive i was always number 15 or so in line. i started to send Whatsapp messages on the 17December 2024 on Monday the 6 January i received a whatsapp response saying the parcel was delivered successfully and an image of the waybill with a signature that i do not know was on it. I email them again and kept on messaging on watsapp every hour, but no joy. i have yet to receive any feedback or a call or an email to explain who they gave my parcel to, without getting identification from.
