Shocked with service of a faulty machine from the Cape Town branch

Absolutely shocking service from Jaco at the Cape Town Branch. I bought a Heatpress machine from them 4 months ago. Today after pressing a ry-shirt and swing the top away to remove the t-shirt, the metal arm broke off the metal arm from the back. A CLEAN break, rust show in the back area were it broke of. Jaco very rude and judgmental accused me of using to much pressure. How is a women's force so much to force metal of metal. I am pressing T-shirt only. But he made up his mind to give me the reason for this faulty product. Absolutely terrible service
