Nabsi Autospares, Klerksdorp

On the 24th of April 2019, I ordered and paid R2000 for an Audi Engine Wiring Loom from Nabsi Autospares, Klerksdorp. They sent me photos of the part and promised to send it as soon as my EFT reflects on their side. When id reflected, they sent me a waybill number to track my parcel but only found out that the tracking number was for a parcel that was sent to Cape Town. I immediately notified them and they said I should wait for them to re-route the parcel to the correct address. I waited for two weeks and when I eventually made another follow up, they sent me another tracking number, which I followed up with the Courier Company and it confirmed that they had the parcel. When the parcel arrived, there was a Golf 3 radiator in the box not an Audi wiring loom as agreed. I immediately called them, alerting them of the error and they promised to look into it, but now they have ignoring my calls to the cell number that was provided to me and when I speak to their sale personnel, no one seems to know anything about my order. Eventually I sent them an email, and their response is that they sent me the correct part, which is a total lie. My car has been standing at the mechanic's workshop and I am being charged for storage, while they are playing games. Please Help, Is there a place that I can go to for help in relation to this?
