Extremely Poor Customer Service & Handling Internal Errors

Placed an online order 28/09/2024, delivered on 01/10/2024 - two parcels:

Parcel 1: My item Parcel 2: NOT MY ITEM

I called the courier company to let them know I received a parcel labelled with my information but the contents is for another customer. They sent their courier to fetch the parcel - I get no proof thereof and now its a hassle to get my 2nd item.

Hi Fi Corp. claims that it has been delivered and I have told them about the incident now I need "proof" - why do I need proof for an internal labeling mistake. I do not have my 2nd item and that's the fact, their system is useless and the call center - just forget about service.

The Centurion branch manager was supposed to call me on Wednesday - we are on Friday and I have not received a call. If I did not reach out to the couriers and to Hi Fi Corp I probably will never receive my 2nd item.

By the looks of it, because of their mistake without "proof" I might not even be able to receive my 2nd item.

I have provided them with my own tracking number as well as the parcel of the other customer (which all the details match correctly on their system) yet I need proof.

Will not buy anything from them again - only due to poor customer service and no urgency in resolving their mistakes.
