Dissatisfied Customer

I have been waiting for my parcel for a little over a week now from Courier IT. It is a parcel from MTN Insurance that was due to be delivered, 1 March 2024. Everyday I call in and they send me back and forth to customer services. No communication is made and when I call in they tell me that it was loaded in a vehicle and is being delivered that day. I requested to collect it myself today and they told me that it was already loaded in a vehicle. I also requested to speak to a manager and they put me on hold for over 10 minutes. I am extremely frustrated and displeased.
