Sa towbar product quality....

I bought a double tube towbar from SA towbar for my 2018 Hilux sc In one week rust is appearing on the top of the inner tube. Upon reporting it they responded by asking me to bring it it to spray over it. I refused. The agreed then for me to bring it in for replacement. When i phoned them this morning to equire if i can com in they told me that they will phone me back...still waiting....i think small ckaims court is the next step... I can see rust bubbles under the plasticote on the tube. Clearly no preparation of material before coating...
