Courier guy or PUDO ****

The courier guy is affiliated with PUDO. A parcel was send using the locker to locker system. According to the tracking system it was delivered to Southcoast mall. The PIN number was provided to the to my colleague to collect, however the PIN number was incorrect. When we contact courier guy at Steller mall in crown mines, they could to assist and passed the buck to PUDO. Tried to contact PUDO vis what's up, the message was delivered and read, however no reply. Send an email to support, however no reply. We paid for a service and to date have not received it and the parcel is not in my possession. Is PUDO or courier guy ******** us, are they wanting us to pay for a service and than keep our parcels. These are traits of poor service or ****? We need our parcel back
