Delivered my order to someone else and doing nothing to correct it

I was expecting my delivery from one Deal A day in 6 June. On that day I received a call from a school in the area confirming that they received my parcel. I phoned fast way to inform them of the error, and the guy in the line argued with me saying that their system shows it has not been delivered. I asked him it was possible that this school had my contact details and described my parcel? He said he would call the driver to find out. He called me back because he forgot why he wrote my number down so I had to explain it to him again.

He did not call back again.

On Wednesday I call fasrway again because now the status is reflecting that my parcel has been delivered. The person on the line said I need to place an online query, so I did. I did not receive any email confirmation that it has been submitted or even a phone call.

What else must I do? My order is valued at R2500 Rand just sitting somewhere else and fastway does not seem to care about their negligence
